this gets the right number of notches on quadplanes, but is still very
bad in fwd flight

Filter: allow for expansion of dynamic filters
...
this allows for the number of dynamic filters on a harmonic notch
filter to expand at runtime, which allows for ESC RPMs to be populated
from other than AP_Motors, such as with lua scripts or for fwd motors
in a SLT quadplane

...
This delegates updates to a bank of NotchFilters located at an rpm frequency and harmonics. Center frequency can be updated dynamically. Notch parameters are configurable, including the number of harmonics to filter on. Updates to the filter parameters are optimized across the notch bank. Convert notch bandwidth and frequency to floats.
allow all filter harmonics to be controlled.
add destructor to harmonic notch.
don't allocate sub-filters for harmonic notch if no harmonics set.
