Test Concurrency

[maddenp-noaa]

Synopsis

Add concurrency to lint and unittest test targets.

Previous times:

• make lint 0m8.276s
• make unittest 0m17.299s
• make test 0m25.268s

New times:

• make lint 0m4.315s
• make unittest 0m6.267s
• make test 0m11.054s

I also updated several test- and run-time packages to their latest versions.

NOTE After this merges and you pull the changes into your fork, you'll need to re-create your devshell. Exit your existing shell, run make clean-devenv to remove the old one, optionally run conda clean --all --yes to clean up old packages and reclaim some disk space, then run make devshell to create a new devshell with the updated packages.

Type

• Code maintenance (refactoring, etc. without behavior change)
• Tooling (CI, code-quality, packaging, revision-control, etc.)

Impact

• This is a non-breaking change (existing functionality continues to work as expected)

Checklist

• I have added myself and any co-authors to the PR's Assignees list.
• I have reviewed the documentation and have made any updates necessitated by this change.

I've never been more thrilled to see a PR in my life.
