Add HEALPix tiled observation submission script
Add new module for common submission routines
Submission: extract prepare_archive_db subroutine
Submission: move assign_to_group and get_obsidss
Submission: move data hashes to module
Submission: move obs_is_fts2_or_pol2_RECIPE
Submission: extract logging routines

Also give the "regular" and SCUBA-2 HPX log files different names
so that they don't overwrite each other.
Submission: extract submit_jobs subroutine
Submission: move documentation of groups hash
Correct spelling of reduction
Remove unnecessary variable
Remove unnecessary imports
jsahpxobs: correct documentation for mode options
Submission: extract find_observations subroutine
jssahpxobs: do not force debug options to off
Submission: extract determine_resource_requirement
Submission: extract adjust_header subroutine
jsahpxobs: reorder to match jsasubmit
Submission: extract determine_frame_class
Submission: allow --ut and --project together

In this case, jsasubmit should run in night mode but only submit
observations from matching projects.
