WBFM integration

[john-]

Here is a first pass at WBFM integration. This also includes splitting out demodulators into their own files. That is a separate commit if it needs to be isolated.

I am still trying to track down a frequency to test WBFM it but there are no errors and audio files are generated (tested only with recording).

Confirming when you said “ tested only with recording” you mean without classification? And that recording was WBFM modulator with NBFM signal, and does save audio. I confirmed that does work. WBFM signal with WBFM modulator also worked. WBFM with classification does not work but likely is just due to re-training need. I will backlog collect signals for a training set.

Yes, I did not test classification. I only confirmed that with the -w options files were written to disk. This was not with a WBFM signal as I think ham2mon will record transmissions even if they are not of the requested type.

This is now merged into master. Based on this thread there may still be open issue with audio classification of WBFM recordings.
