* 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
replaces the pixel magic tool with a much more feature-rich tool for handling gif images. Also adds a scrolling text interface and the possibility to add more tools with a single button click like the classic pixel magic tool and the pixel-painter tool.
- Renamed hasPSRAM field to psramPresent in /info endpoint (json.cpp)
- Updated usage report to use psramPresent field (index.js)
- Removed problematic _codeql_detected_source_root symlink

- Modified reportUpgradeEvent in index.js to use new hasPSRAM and psramSize fields
- Changed from calculating psramSize from free PSRAM to using total PSRAM size from /info endpoint
- Both fields now correctly sent in upgrade usage reports to usage.wled.me

- no mendatory external JS dependency, works in offline mode
- optional external dependency is used for highlighting JSON, plain text edit is used if not available
- WLED styling (dark mode only)
- JSON files are displayed "prettyfied" and saved "minified"
- JSON color highlighting (if available)
- JSON verification during edit and on saving both in online and offline mode
- special treatment for ledmap files: displayed in aligned columns (2D) or as lines (1D), saved as minified json: no more white-space problems
- displays file size and total flash usage
- Enabling DDP over WebSocket: this allows for UI or html tools to stream data to the LEDs much faster than through the JSON API.
- first byte of data array is used to determine protocol for future use
- Moved the duplicate function to establish a WS connection from the live-view htm files to common.js
- add better safety check for DDP: prevent OOB reads of buffer

Implement a comprehensive solution for validating a firmware before an
OTA updated is committed. WLED metadata such as version and release
is moved to a data structure located at near the start of the firmware
binary, where it can be identified and validated.

- 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
