* use sequential loading for all UI resources
- load common.js and style.css sequentially for all config pages
- restrict all requrests in index.js to single connection
- retry more than once if requests fail
- incremental timeouts to make them faster and still more robust
- bugfix in connectWs()
- on page load, presets are loaded from localStorage if controller was not rebooted
- remove hiding of segment freeze button when not collapsed
- 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

* Attempt at better bus memory calculation and estimation
* Remov double buffer count for ESP8266 (thanks @dedehai)
* improve UI calculation
* adding mendatory LED buffers to UI memory calculation
* adding buffer for transitions to memory calculation, change "error" to "warning"
* bugfixes in settings_leds.htm
* fix getDataSize() forESP8266, ESP8266 does not use double buffering.
* update led settings: fix parsing by @blazoncek
* new warnings for LED buffer use, deny adding a bus if it exceeds limits
* adds recommendations for users (reboot, disable transitions)

* 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
* Make color_wheel rotate in HSV sapce instead of linearly interpolating R->G->B
* Remove the rainbow wheel option, as that is the same as the rainbow palette
* Use hsv2rgb for color_wheel
This is the current result of the discussion in https://github.com/wled/WLED/pull/3681
- 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)
- 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
When adding a new bus, the numeric current limit field was not being
initialized; this was causing it to save 0 when saved instead of the
default 55mA value.
