GMSK/GFSK also needs faster filtering due to convolution of long signals with gaussian pulse shape #85

Much computation required to apply pulse shaping filters for narrow bandwidth signals with a high oversampling rate (large samples per symbol). Run time could be improved via either:

FFT-based convolution, or
Multi-stage sample rate change (ex: generate signals at 4 samples per symbol and then resample to the desired SPS)
