How to talk to the mutesync button.

mutesync_serial.js

// The API is really simple, to control the lights you send the button a byte array of 13 bytes.
// The first byte needs to be 65 and the rest of the twelve bytes are 3-tuples (RGB values 0-255 for the individual LEDs).
// So alternating red and green lights would look like

[65,
 255, 0, 0, // red
 0, 255, 0, // green
 255, 0, 0, // red
 0, 255, 0] // green

// When the button is pressed it sends the byte `51` and when it's released it sends the byte `52`.
