Odroid C4 support

[Travis Hardiman]

I am running Hyperion on a Odroid C4 under Odroid's Ubuntu Mate install, however I get an error when using ws281x:
2023-04-03T01:42:37.890Z [LEDDEVICE|First LED Hardware instance] (ERROR) Device disabled, device 'ws281x' signals error: 'Failed to open. Error message: Hardware revision is not supported'

Here is more info on the header pins:

This library does not and will not support Odroid boards, it's too closely coupled to the Pi hardware and reliant upon specific combinations of peripheral features.

@dieseltravis Made Odroid c4 adaptation of hepingood/ws2812b (it uses SPI MOSI pin to modulate necessary signals), hope that's helpful. Will try to improve timings as there are still some noticeable artifacts.
