There are basically two types of ws2812b strips: RGB and RGBW, the latter having a seperate white LED.

The former we support, the second we should support as well.
There are two stages to support this:

  • Make it use RGB only, padding the fourth byte.
  • Extrapolate the white byte by the RGB values, trying to mix it as best as possible.
    • Need to make sure the brightness is correct.
