Dmitry Butyugin 57494458f3 shaper_calibrate: Ignore vibrations below max_psd / 20 threshold
The input shaper can only reduce vibrations by 20x. Therefore,
the best-case achievable vibrations level is max(psd) / 20.
Any vibrations below that level can be ignored for the prupose
of input shaper scoring. This allows tuning script to ignore
wide tails of resonances, because it is not helpful to try to
reduce them with input shaping.

Dmitry Butyugin 1b1a97e8bd shaper_calibrate: Choose input shapers accounting smoothing
Improved algorithm to choose the 'optimal' shaper frequency taking
shaper smoothing into account. This may choose a frequency with
slightly more vibrations but less smoothing. Also allow users to
limit the maximum input shaper smoothing.
