scripts: Added shaper tuning parameters to calibrate_shaper script
The added parameters include square_corner_velocity, shaper frequencies
to optimize, input shapers to test, input shaper damping ratio and
damping ratios to test. All these options can be useful for fine-tuning
the input shapers when the default suggestions generated by the tuning
script are not optimal.
Also the `SHAPER_CALIBRATE` command was modified to pass some of these
parameters to the shaper tuning routine. Specifically, square corner
velocity and the maximum tested frequency are used to adjust shaper
tuning and maximum acceleration recommendations.
