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.
