Add ID command

[Eiren Rain]

An ID command sent from the server should force tracker to light up the LED for identification. Command can contain trackerId but the tracker can ignore it if there are no way to identify only extension. Command should be acknowledged by replying it back to the server. Another command with state off should stop the process and again be acknowledged to the server.

Add ID command to tracker

This should be added into the new protocol tbh, there's no need to change the current netcode just to add this and then reimplement it later.

-> Waiting for new protocol
