pypeit/PypeIt: Version 1.11.0

Significant Updates Add ability for users to specify custom arc line lists for wavelength calibration, saved in the user's PypeIt cache Allow for the specification of a specific UVIS extinction file for sensitivity function computation and flux calibration. Now more than one setup can be assigned to the same calibration frame, allowing to associate the same calibration frames to different science/standard frames, if desired. Refactor and general update of documentation Instrument-specific Updates Correctly associate calibrations with science data for MOSFIRE longslit and long2pos masks. Automatically assign comb_id and bkg_id to MOSFIRE science data, using the information on the dither pattern. Minor Added Keck/NIRES frame-typing development doc. Allow verbosity specification for various post-processing command-line scripts.
