Title: Add tests for filter design

This confirms the correctness of our results and compares accuracy vs. MATLAB for all but the bilinear step in digital filter design. I am a little suspicious that bilinear step is not particularly numerically precise, but I have no good way of testing that at the moment, since I can't perform the calculations with extended precision.
