Is your feature request related to a problem? Please describe. Slow rational resampling

Describe the solution you'd like Put rational resampling in a dsp module and use exponential filters for related filtering.

Describe alternatives you've considered Just using polyphase_resample from scipy

Additional context Related to #124

Attempting to accelerate beyond sp.resample_poly using custom usage of sp.upfirdn was not fruitful.
