New sodetlib version fixes bug in time constant analysis for detectors near saturation, and provides additional configuration parameters to control amplifier biasing.
Description
fit_tmin is again available as a parameter that can be specified. If left as None, dynamic tmin calculation is used.
Dynamic tmin calculation rewritten to rely on the stored polarity of a detector's response, rather than abs(signal)
For amplifier bias parameters,
amp_{amp}_gate_volt_{min/max}are added to the dev cfg and referenced in the amplifier biasing routines.Motivation and Context
Issues with time constant fitting of near-saturated detectors shown here:

How Has This Been Tested?
Kyohei and Daniel have re-run bias step analyses and saw the spuriously-low time constants disappear, with results similar to the old fixed tmin=1.5 ms results.
