[hpsdr] SDR-1000 interfacing

[Alex]

If we're worried about having too many connectors for the SDR-1000 and where to locate them. 
Doing a little outside of the box thinking, why don't we take the SDR-1000 stack, eliminate it's 
I/O board and take the rest of the stack and turn it into a daughterboard for JANUS.

Then we don't have to worry about tiny audio connectors nor a clunky DB-25 interface.
