out_rpi_ws2812b: RGBW support #20

Open vifino opened 6 years ago

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.
