Auto-calculate white channel from RGB modes

Accurate will subtract the calculated white value from the RGB channels which gets rid of the "RGB-white" but means that the light is less bright with only the white channel and not the RGB channels being utilized for pure white.
Brighter will do the exact opposite and not touch the RGB channels at all, just mix in the dedicated white.
Dual and None will display a white channel slider in the UI to set the value manually, but when set to 0 the white channel will be off in None mode and use the Brighter calculation method in Dual mode.
Lastly, Legacy is the old method. It only applies to the 3 main colors, but is also quite accurate. Accurate and Brighter methods are applied on a per-pixel basis, so they also work in color palettes!
