I should commit more often. Added EDACS decoding. Rejiggered the
filterbank into its own class (still haven't split up radio.py). This
should make it about 2x faster in those big polyphase decimators. Still
having trouble getting the demod to work at low sps, current resamples
up to 3sps and then demods.
Finally split radio.py into subfiles. Should add GPL in there.
Forgot to add the invert block source.
Strip out unused imports, remove dual-tuner UHD code
