output messages have the same arguments as they do in [monome OSC](https://monome.org/docs/serialosc/osc). Each argument is given as a byte and the message type is a byte. The message types are:
so to send a `led/set 1 2 1` message, send the bytes `0x00 0x01 0x02 0x01` to the out program (if you are using this in a pipe with uxn, this is `.Console/write`)
