per-point switching: hardware bring-up, profiles, protocol doc

Browse Source 
Verified on the bench that the modified master bitstream excites in every stage
and the RF switch routes: 16 traces per sweep, 62 dB between the two switch
positions of one master port, 9.9k measurements/s. Adds the built master image,
two run profiles, a verification script and librevna_protocol.md, and drops the
stale prototype driver copy that the firmware tree still carried.
