MQTT support

[davyhollevoet]

Have you considered adding support for controlling pixelblaze over MQTT?

My use-case is connecting it to Home Assistant, which supports controlling lights over MQTT. Right now I'm using a small python bridge between MQTT and the pixelblaze websocket: pixelblaze_mqtt_bridge (shameless plug)

I've given it a shot, but the libraries I used hogged CPU and resources and kind of ruined the whole smooth LED thing so I dropped it and focused on other things. I'll give it another try at some point for sure. Thanks for the bridge, that could help a lot of folks in the meantime!
