Title: Filter docstring additions

- add parameters and returns to all matlab-style filter docstrings
- fixed default bandpass mistake in butter()
- missed some while changing `analog` to boolean
- remove "lowpass" from descriptions since they all do all types (`iirfilter()` is actually bandpass by default)
- clarify units (dB, rad/second vs rad/sample)

Please double-check the accuracy of these, I made a mistake the last time
