Deprication warnings fixes made to iir_design_helper. Significant additions made to digital_com to support Gray encoding and decoding for QAM and MPSK moduation and demodulation at the bit level. Supporting functions for nonnegative decimal values to and from numpy binary arrays, gray2bin and bin2gray, and bit and symbol error probability (BEP/SEP) for QAM and MPSK in terms of Eb/N0 or Es/N0.
