DMX512/sACN/E1.31 support (#184)
* Started on support for sACN/E1.31/DMX512 Just a clone of udpraw for now * It's ALIVE!! This adds somewhat working DMX512/sACN/E1.31 support. I've tested it against an ESPixelStick but have no other "real" hardware TODO: configure universe# configure universe and led offset configure source names (all hard coded now...) * oops.... forgot that dmx element 0 isnt rgb data but needs to be zero * added universe support in the config assorted code cleanups
