Checklist

• Invalid trove classifier, BSD 3 Clause. See list here: https://pypi.org/classifiers/
• Since this is ambiguous, this adds a license_expression per https://peps.python.org/pep-0639
• Notably, since these never would build, there isn't a need to update a version number since they must never have deployed

Testing Instructions

[bleggett]

The python is generated code, but not linted as part of CI, correct - that can be added.

Relatedly, I think I dorked up the CI gates - all previous PRs have a validated passing CI gate but this one skipped - investigating.

Fixed the CI gate - tho you can see for each PR if ci_gate passed, I think the repo settings weren't explicitly requiring ci_gate to pass before allowing merge - that is fixed.

Build fix here: #18

Thx guys!
