* 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
