This PR contributes some bookkeeping updates for computing biases and darks, documenting what was used for the 20210130 update to desi_spectro_calib for the new CCD timing files.

  • desi_compute_bias --expfilelist option to specify input NIGHT EXPID in a file instead of N>>1 paths to raw files on the command line
  • desi_compute_dark_nonlinear option to group darks with zeros by NIGHT (rolling over at noon, allowing a nighttime dark sequence to span midnight) vs. the previous grouping by DAY (rolling over at midnight, allowing a daytime dark sequence to span noon). Either is supported now by specifying either --days or --nights
  • desi_compute_dark_nonlinear --first-expid option to specific the first exposure ID to use (e.g. to exclude test exposures with a different configuration earlier in the night).

And coming along for the ride is a bug fix to desi_compute_psf --specmin bookkeeping (it wasn't working for specmin>0). This isn't required for normal pipeline operations, but is handy for debugging when PSF fitting a single bundle.
