JP-4289: Define supported SOSS subarrays in jwst.lib

[melanieclarke]

Toward JP-4289

Add a list of supported SOSS subarrays to jwst.lib.exposure_types and use it to replace some duplicated hard-coded lists in various places.

This seemed like a reasonable place to define the list, since there are other similar constants in that module, but I'm open to suggestions if somewhere else is preferable.

I also added the existing constants to __all__ since they are imported elsewhere.

Tasks

• If you have a specific reviewer in mind, tag them.
• add a build milestone, i.e. Build 12.0 (use the latest build if not sure)
• Does this PR change user-facing code / API? (if not, label with no-changelog-entry-needed)
  • write news fragment(s) in changes/: echo "changed something" > changes/<PR#>.<changetype>.rst (see changelog readme for instructions)
    • if your change breaks step-level or public API (as defined in the docs), also add a changes/<PR#>.breaking.rst news fragment
  • update or add relevant tests
  • update relevant docstrings and / or docs/ page
  • start a regression test and include a link to the running job (click here for instructions)
    • Do truth files need to be updated ("okified")?
      • after the reviewer has approved these changes, run okify_regtests to update the truth files
• if a JIRA ticket exists, make sure it is resolved properly

A couple unrelated failures from network blips; otherwise, all passing.

Thanks for cleaning up! My only comment/question is whether you think exposure_types is an ok namespace for subarrays, or if it's a technicality not worth worrying about

I thought it was close enough -- "exposures with acceptable subarrays" is a sort of sub-type for NIRISS SOSS. Maybe someday we can work on reorganizing the lib utilities to make more meaningful namespaces.
