* Started implementing artnet/DMX support
It compiles, but certainly wont work just yet
* Fix up packet data and length
correct default udp port
The data looks ok in wireshark
* Code cleanup
Sequence runs from 1..255 not 0
fix universe > 255
* code cleanups and force even number of channels
* Fix potential endianness issue
* added support for 'x' channels per fixture with zero padding
its very basic support for now - it needs better multi universe support
