SCRIPTS: Fix mix-up between normalized/unnormalized cutoff frequencies

- Now all filters are parameterized with a normalized cutoff frequency,
e.g. 0 to 1

FILTERS: Add the implementation for low-alias nonlinear Moog filter

To be considered as bleeding edge. Current issues:
- very high output DC
- bad ranges
Basically, everything fails for now.
