Description

Fixes #10882, this removes parallel keyword from the cparser. As this has been broken for a long time and the code has been raising warning for some time now so I guess we probably don't need to go through the deprecation cycle.

Thank you for your contribution to Astropy! 🌌 This checklist is meant to remind the package maintainers who will review this pull request of some common things to look for.

  • Do the proposed changes actually accomplish desired goals?
  • Do the proposed changes follow the Astropy coding guidelines?
  • Are tests added/updated as required? If so, do they follow the Astropy testing guidelines?
  • Are docs added/updated as required? If so, do they follow the Astropy documentation guidelines?
  • Is rebase and/or squash necessary? If so, please provide the author with appropriate instructions. Also see instructions for rebase and squash.
  • Did the CI pass? If no, are the failures related? If you need to run daily and weekly cron jobs as part of the PR, please apply the "Extra CI" label. Codestyle issues can be fixed by the bot.
  • Is a change log needed? If yes, did the change log check pass? If no, add the "no-changelog-entry-needed" label. If this is a manual backport, use the "skip-changelog-checks" label unless special changelog handling is necessary.
  • Is this a big PR that makes a "What's new?" entry worthwhile and if so, is (1) a "what's new" entry included in this PR and (2) the "whatsnew-needed" label applied?
  • At the time of adding the milestone, if the milestone set requires a backport to release branch(es), apply the appropriate "backport-X.Y.x" label(s) before merge.

We'll need to rely on tests to be sure this is OK, but it basically looks good. It looks like there are a few remaining parallel references:

➜  ascii git:(pr/MridulS/16103) pwd
/Users/aldcroft/git/astropy/astropy/io/ascii
➜  ascii git:(pr/MridulS/16103) find . -type f | xargs grep -i parallel
./tests/test_c_reader.py:    # test_for_warnings = fast_reader and not parallel
./tests/test_c_reader.py:    # if not parallel and not fast_reader:

➜  ascii git:(pr/MridulS/16103) cd ~/git/astropy/docs/io/ascii 
➜  ascii git:(pr/MridulS/16103) find . -type f | xargs grep -i parallel
./fast_ascii_io.rst:Parallel and Fast Conversion Options
./fast_ascii_io.rst:  Parallel and Fast Conversion Options for Faster Table Reading

This also needs an API change log entry.

Unfortunately a Wheel building CI failed which is presumably unrelated. Since CI needs to run again, there is one tiny thing I'd like to fix.
