[Feature Request] Would it be possible to add RGB LED support?

[VitroidFPV]

I got FAK running on an AliExpress 3x2 macro pad after some messing around and it's great now! The original configuration software was really annoying to use. Now... this board has RGB backlighting for each key, I was wondering if it would be possible to add support for WS2812 (neopixel) LEDs. Doesn't need to be anything fancy, even just a "dumb" solid color backlight would be awesome!

EDIT: Would also be really good to bind to layers to work as an indication. Really lovely kb firmware tough, thanks for all the work!

fwiw: I'm working on this over at https://github.com/dominikbayerl/fak/tree/feat/led

Awesome work! I'm trying to get this working for split keyboards. So far I've modified some of the nickel configs and have the neopixel code being compiled on both halves, but it looks like there will need to be some kind of syncing of LED state between them.
