P25 demod support

[sparklespdx]

I'm mostly creating this issue to gauge interest in a P25 plugin for sdrangel. It is certainly something that has been done before, more recently: http://osmocom.org/projects/op25/wiki.

I'm new to signal processing, I think that listening to P25 is pretty cool and I am interested in seeing what it would take to create this plugin.

The main point is to make it a feature of dsdcc: https://github.com/f4exb/dsdcc
Then there is a little work to integrate the status messages specific to P25 in DSD demodulator.

Totally makes sense. Seems like I should add an issue to that repo?

Yes please. In fact I did not open it myself since I have other priorities. Consequently I cannot promise a quick implementation. It just happens that MMDVM has P25 support so provided I can switch on a P25 reflector and it has some traffic I would be able to get sample frames. I recently did the same thing for NXDN.

I actually would like to get up to speed and learn how to conbtribute this myself! I'll make an issue in the other repo.
