LimeSDR under SDR-Console

@martywittrock Are you able to use HF on the version 1.2 board + GQRX as you were before with the current software? I found a bug that involves the NCO sign swapping on the new hardware rev (its just flipped register-wise and needs the software to compensate). This affects anything using SoapySDR layer tuning below 30 MHz. So I just fixed that in the git repository.
