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.
