Updated the message formats, rewrote the main loop to handle the callback function, wrote the Iridium send/receive code, wrote command receive code, added several variables to the Persistant namespace. Untested but compiles.
Fixed a misplaced curly bracket.
Set up to send cmdcontrol messages right now for diagnostic purposes. Also moved the diagnostic communication into the callback function so that it does not block.
Moved satcom initialization code to the loop so that the callback will only ever be called after the setup function has completed.
Few small changes.
