Added support for enterprise WiFi.
* Updated based on feedback from CodeRabbit.
* Fixed issue with strncmp identified by CodeRabbit.
* Replaced split declaration-then-assignment with a single statement.
* Revert whitespace only changes.
* Move WPA enterprise behind a feature flag.
These changes eliminate an elaborate race condition
* add dedicated function to handle on/off and relay
* add clarifying comment on output set order
* add define for relay delay, honor forceOff in all cases
* full refactoring, added live preview, better minifying in cdata.js
* update main UI buttons, support for gaps in cpal files, cpal UI cleanup
* fixed some layout issues, added un-ordered cpal deletion
* changed to tab indentation, paste button border color now holds stored color
* fix preview to work properly and some other fixes in UI
* always unfreeze
* new approach to loading iro.js, add harmonic random palette, many fixes.
* decoupling iro.j, update UI of cpal.htm
- load iro.js sequentially
- no parallel requests in cpal.htm
- update UI buttons
- fix showing sequential loading of palettes (using opacity)
- better UX for mobile (larger markers, larger editor)
- various fixes
* small change to buttons
* load iro.js dynamically, remove iro.js from index.htm, revert changes to cdata.js
* improved visibility for very dark/black palettes and markers
- speed optimization in color_add, PS fast_color_add and blur functions
- applying more bit and shift manipulation tricks to squeeze out just a bit more speed on color manipulation functions.
- Optimization on blur is based on work by @blazoncek
- Renamed PS fast_color_add() to fast_color_scaleAdd()
- allow more than 10 custom palettes
- move palettes into CPP file
- Fix for minimizing cpal.htm (saves 2k of flash)
- shortened names in cpal, saves about 400 bytes of Flash after packing
- removed async from common.js loading to prevent errors on page loads if the file is not cached
- restricted nubmer of user palettes on ESP8266 to 10
- unrestricted number of user palettes on all other platforms (total max palettes: 256)
- added a warning when adding more than 10 palettes to let the user decide to risk it
- Bugfixes in palette enumeration, fixed AR palette adding
- AR palettes are now also added if there are more than 10 custom palettes

* Improved heap and PSRAM handling
- Segment `allocateData()` uses more elaborate DRAM checking to reduce fragmentation and allow for larger setups to run on low heap
- Segment data allocation fails if minimum contiguous block size runs low to keep the UI working
- Increased `MAX_SEGMENT_DATA` to account for better segment data handling
- Memory allocation functions try to keep enough DRAM for segment data
- Added constant `PSRAM_THRESHOLD` to improve PSARM usage
- Increase MIN_HEAP_SIZE to reduce risk of breaking UI due to low memory for JSON response
- ESP32 makes use of IRAM (no 8bit access) for pixeluffers, freeing up to 50kB of RAM
- Fix to properly get available heap on all platforms: added function `getFreeHeapSize()`
- Bugfix for effects that divide by SEGLEN: don't run FX in service() if segment is not active
-Syntax fix in AR: calloc() uses (numelements, size) as arguments
* Added new functions for allocation and heap checking
- added `allocate_buffer()` function that can be used to allocate large buffers: takes parameters to set preferred ram location, including 32bit accessible RAM on ESP32. Returns null if heap runs low or switches to PSRAM
- getFreeHeapSize() and getContiguousFreeHeap() helper functions for all platforms to correctly report free useable heap
- updated some constants
- updated segment data allocation to free the data if it is large
- replaced "psramsafe" variable with it's #ifdef: BOARD_HAS_PSRAM and made accomodating changes
- added some compile-time checks to handle invalid env. definitions
- updated all allocation functions and some of the logic behind them
- added use of fast RTC-Memory where available
- increased MIN_HEAP_SIZE for all systems (improved stability in tests)
- updated memory calculation in web-UI to account for required segment buffer
- added UI alerts if buffer allocation fails
- made getUsedSegmentData() non-private (used in buffer alloc function)
- changed MAX_SEGMENT_DATA
- added more detailed memory log to DEBUG output
- added debug output to buffer alloc function
- Bugfixes in FX data allocation: realloc was not handled properly.
- Added *intermediate* fix for waitForIt(), see https://github.com/wled/WLED/issues/4779
- Bugfix in 1D->2D expansions: corner-expansion MUST be boundary checked as it blindly writes the max dimension
- removed some realloc(), improving fragmentation on large setups
- increased min heap constant
- ESP32 C3 has no PSRAM, it now uses default alloc functions
- also added missing UI info for "Error 7"
- Photoshop-style segment/layer blending
- return of strip ABL
- remove global LED buffer in favour of segment-local buffer
- new effect blending modes/transitions
- custom palettes moved out of WS2812FX class
- increased limits (matrix size, LED RAM)
- added "rainbow"-mode colorwheel
- replaced palettes with gamma unmodified ones
- move gamma adjustment to last step before sending to LEDs
- Segment & WS2812FX class reorganisation (mutable members, reordered members, protected members)
Enable the new concurrent request and queue size limit features
of AsyncWebServer. This should improve the handling of burst
traffic or many clients, and significantly reduce the likelihood
of OOM crashes due to HTTP requests.
- Implement vector in bus manager
- Memory calculation according to explanation from @Makuna
- Prefer 8 RMT before 8 I2S on ESP32 (fixes#4380)
- speed improvements in ABL
- verbose debugging
- get bus size from NPB (prototype)
- Parallel I2S output bugfix
- automatic selection of appropriate I2S bus (`X1xxxxxxMethod`)
- removed I2S0 on ESP32 (used by AudioReactive)
- renumbered internal bus numbers (iType)
- added buffer size reporting
* DeepSleep Usermod
- sleep delay is now 1 by default, disabling sleep at powerup
- renamed bootup variable to powerup
- using delay counter for proper bootup
- changed power-up and bootup logic
- added fallback to always power-on at boot except at powerup
- fixed bug in settings page
Improvements & merges of FX
- Scrolling Text: Gradient Palette support added
- Waving Cell: Improved with higher temporal resolution (smoother at lower speeds) and added additional mode setting and optional blurring
- Julia: added blur option
- Squared Swirl: added fade option
- Added smearing option to:
- DNA
- DNA Spiral
- Drift
- Drift Rose
- Crazy Bees
- Ripple
- Colored Bursts
- Frizzles
- Lissajous
- Sindots
- Spaceships
- Added palette support to:
- Crazy Bees
- Polar Lights
- Drift Rose
- Changed default palette handling (no more special treatment for some FX)
- Merged puddles and puddlepeak
- Merged Gravcenter, Gravcentric, Gravfreq and Gravimeter (saves 1.2k of flash)
- Merged meteor and meteor smooth
- Renamed police_base into mode_two_dots as that was just an alias
- Added 'Traffic Light' palette (originally defined in Polar Lights FX)
- Firenoise: removed local palette, use fire palette -> slight change in looks (+bugfix)
- Some code cleanup (removed unused / commented stuff)
- Moved dev info for AR to the top so ist easier to find as a reference, also added link to KB there
- increase WLED_MAX_BUSSES for C3 (fixes#4215)
- fix for #4228
- fix for very long running effect (strip.now, strip.timebase)
- C++ API change to allow `seg.setColor().setOpacity()`
- Renamed LEDPIN to DEFAULT_LED_PIN.
- Removed ability to override DEFAULT_LED_PIN, DEFAULT_LED_TYPE and DEFAULT_LED_COUNT. Use DATA_PINS, LED_TYPES and PIXEL_COUNTS instead.
some users have reported that releases after 0.14.0 are not working reliably. So we add a few "compat" for 8266 that try to reproduce the buildenv of 0.14.0 as much as possible.
* platform and platform_packages from 0.14.0
* not using PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48
* due to smaller IRAM, we had to move some functions back from IRAM to normal flash (may cause slowdown)
