New plugins
This is quite a rich release so let's detail these new plugins:
ADS-B demodulator and decoder
Again a very nice contribution from Jon srcejon. This plugins demodulates and decodes ADS-B frames and shows the data in a table and also shows the aircrafts positions on a map. It can report the selected plane azimuth and elevation from the given user location via the report endpoint of the REST API thus combined with the GS-232 feature plugin (See next) it can steer an antenna pointing at the plane. More information and interface description can be found here. PR #671
GS-232 interface
Also a nice contribution from Jon srcejon. This feature plugin can be used to control a GS-232 steering device via serial interface. The position can be set manually or polled from another plugin like the ADS-B demodulator above. More information and interface description can be found here. PR #671
Automatic Frequency Control
This feature can be used to close the loop between a Frequency Tracker plugin and the channels that we want to control thus effectively making an AFC system, It would be particularly useful to compensate for LNB slow drift in QO-100 typical installations. More information and interface description can be found here. The functionality is very similar to what we already had here but integrated as a feature plugin. Implements #634
