===========================================================
Multicast UDP broadcast containing rig snapshot data
Bidirectional rig control and status
Choice of token pairs or JSON
All packets will be tagged with ID=[unique name] -- so multiple rigs can broadcast/rx on the same port
Will eventually be able to set freq, mode, width, ptt, satmode, and split to start since those are common to many apps.
More functions will be added as time goes on.
Broadcast packet contents to be based on get_rig_info output
Can be multiple VFO lines
Parsers should allow for unknown tags that may be added in the future
Rig command: \get_rig_info
VFO=Main Freq=145000000 Mode=None Width=0 RX=1 TX=1
VFO=VFOB Freq=145000000 Mode=FM Width=15000 RX=0 TX=0
Split=0 SatMode=0
PTT=1 (1=On, 0=Off)
Rig=Dummy (name of connected rig)
App=Hamlib (name of application providing the packet)
Version=20210429 1.0.0 (version YYYYMMDD)
Status=OK (possible values OK, Offline, Error)
ErrorMsg=msg text (pipe delimited multi-line error message)
