* Implement more palette features (like configuration of the keyers)
* Detect switcher type and firmware version in library
* In runloop, detect if connection is kept open (maybe mimick how the PC software is also sending keep-alive packets every half second), and if down, try to reconnect automatically. This is more nice-to-have - a reconnection can easily be established with a hardware reset of the Arduino.
* Look into a possible bug in the UDP library of Arduino - one that may cause buffer overflows and resulting non-connection to ATEM switcher
