Sothoth

• Using SDSS_ID to confirm uniqueness in coadding - Using meta data associated with the latest catalogid observation
• Fixed Flux Distortion Correction Bug (now off by default)
• Modify to fiber flat by padding ends with fixed screen flats to recover full LCO blue coverage
• fixed Chi2 Calculation that caused crashes in Allepoch Coadding
• masking of fibers where tracing failed, resulting in a sigma=0 with trace (which still was extracted)
• Coadding algorithm updates:
  • Merging fibermask in coadding
  • Exclude fiber exposures from coadd if they have bad trace, bad flat, bad arc, no plug, or no data
  • slightly modified so we are not coadding targets where the fiber is assigned but off-target/masked in all exposures
  • still coadding unassigned fibers
• Improved Python logger
• SOS Bright Time BOSS Only Ops modifications (and other functional improvements)
• Modifications in spPlan code to help handle cases with alternative arcs (add added code/par files to support)
• further updates/cleanup to code for updated file organization
• Fixed bug that kept TraceFlats from being used in v6_2_0
• Fixed single fiber bundle extraction bug
• added date-obs header keyword back to spec files
• Add code to support ToOs
• Update readplugmap code for no database access
• Added dustmaps.edenhofer2023 as a backup if simple_dust_2023 (currently proprietary) is unavailable 
• Updates to readtheDocs
• Fixed TNULL values
