Filter: Alter Notch filter formula to remove /0 and allow perfect notch.
...
This formulation of the notch equations lets the user specify the depth of the Notch. The presence of a diveide by A prevents the gain going to zero and therefore achieving a perfect notch. It also provides the risk that a user may attempt to do this and cause a divide by zero error. This change adds the ability to achive a perfect notch and removes the possibility of a divide by zero.

Filter: New HarmonicNotchFilter
...
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.
