SNR Comparator only works for BPSK #2

When using the default SNR estimators for PSK signals, it seems that we only get desired output when we use the imaginary components of the SNRs. A workaround for this is that we currently choose the smaller value, however, this is limiting our ability to work with other modulation schemes such as QPSK.

Created a dedicated selective combining block for BPSK and another block for M-PSK schemes. It seems that the general M-PSK block still has some issues with it.
