[hpsdr] ozy/janus as soundcard for digital modes

[Stephen West-Fisher]

I was thinking (big picture) of creating a new solution and using the
projects and code from PowerSDR as much as possible. Perhaps just creating a
simple UI for debugging and setup. Then once I get it working we can see how
it could be best folded into the larger solution. Thanks for the description
of the flow!

To relevant PowerSDR code for pulling data out of Janus is down 
in  JanusAudio.dll  - the main loop of that is io-thread.c  - it 
essentially reads frames from Janus, parses out the command and 
control bits and builds up buffers of samples that then get passed up 
to the via a callback.    The callback used is Callback3port in 
audio.cs which eventually gets the samples in and out of the DSP.

I think basically what one could do is use the PowerSDR or Kiss code 
to read from Janus and then write into VAC  - then you could get data 
out of Janus and into a program expecting to talk to a windows sound 
driver w/o doing a windows sound driver for Janus.
