* updated color scaling to preserve hue at low brightness resulting in much better colors
* replace NPBlg with NPB, moved brightness scaling to bus manager
* improved gamma table calculation: fixed mismatch in inverting gamma table calculation: inversion should now be as good as it gets
* code cleanup, fixed gamma being applied in unnecessary places
Improvements to ABL handling:
- removed strip level handling, ist now all done on bus level
- limiter now respects pixel mapping
- proper handling of white channel
- improved current estimation
- current is now always correctly reported to UI
- minimal FPS impact if the ABL is not limiting but slighly higher impact for global ABL limit due to double-scaling
- moved brightness scaling to BusDigital
- created new header file colors.h to be able to access color functions in bus-manager.
- updated colo_fade() with better video scaling to preserve hue's at low brightness
- added IRAM_ATTR to color_fade (negligible speed impact when compared to inline and benefits other functions)
- added IRAM_ATTR to color_blend as it is used a lot throughout the code, did not test speed impact but adding it to color_fade made it almost on-par with an inlined function
Additional changes:
- fixes for properly handling `scaledBri()` (by @blazoncek)
- also use bit-shift instead of division in blending for ESP8266
- improvements for faster "softlight" calculation in blending
- changed some variables to uint8_t to maybe let the compiler optimize better, uint8_t can be faster if read, store and set are all done in uint8_t, which is the case in the ones I changed
- various minor code formatting changes
- 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
NeoPixelBus requires that all parallel I2S bus members be constructed
before any of them call Begin(). Implement this by deferring the
call to the end of bus construction.
Fixes#4301.
- update NeoPixelBus to v2.8.0
- use single/mono I2S + 4x RMT for 5 outputs or less
- use parallel x8 I2S + 8x RMT for >5 outputs (limit of 300 LEDs per output)
- increased outputs to 17
- increased max possible color order overrides
- use WLED_USE_PARALLEL_I2S during compile
WARNING: Do not set up more than 256 LEDs per output when using parallel I2S with NeoPixelBus less than 2.9.0
* Add UCS890x support.
* Fixes
* Update NeoPixelBus to 2.7.3 for UCS8904 support.
Update ESP8266 core to 4.1.0
* ESP8266 compile fixes.
- use PlatformIO framework and toolchain
- add compiler warning suppression
- remove IRAM_ATTR to fit in IRAM
* Replace NeoPixelBrightnessBus with NeoPixelBusLg
Resolves#3087
* Update to NPB 2.7.4
* Internal NPB color conversions.
* Fix errors due to merge with SPI Hz methods

* Support white addressable LED strips
* Various white handling tweaks
Allow RGB controls for white-only busses depending on AWM (makes palette-only FX work on non-RGB addressable busses)
Fixed RGB controls hidden if segment contained any non-RGB bus (even though there is also an RGB bus in that segment)
New Max auto white mode
Added hasCCT() bus method
Rename methods to be clearer
WS2811 White getPixelColor fix()
* Fix merge conflict (bus manager cpp)
