Refactor compound call structure for directed messaging by using a new frame type FrameCompoundDirected. This allows us to send only two frames when each station has a compound callsign. No aliasing, full calls are sent with each transmission.

Added varicode encoding of messages
...
What this does is allow us to pack more than 13 characters in a single
transmission frame. Optimized using a Huffman encoding using weights of
alphabetical frequency, this will often allow us to send less than 5 bits
per character.
