Add 1bit SDR #3

Use a pair of LVDS pins as a very fast 1-bit ADC. The setup is antenna -> balun -> lvds pin pair. Currently the code samples at 288MSPS, 144MHz DDR and decimated 8x down to 36MSPS.

I can receive broadcast FM with decent audio quality with this. Adding an LPF for some reason didn't work, the FM signals are still there, so can't tell whether I can receive shortwave.
