* 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
