RPi e1.31 bridge to WS2811 or APA102 strips

sudo ./e131bridge

sudo ./e131bridge --config=../config/config-sample.yml --verbosity=info --stats=true

Because a e131 universe can only support 512 bytes (channels) of data we must use multiple universes to assmeble any signficant amount of LED's. This software supports mapping from multiple e131 universes to a single strip. The mapping configuration is defined in as yml file.
