ml-dsa: exclude tests/ in published crate due to size

[json420]

This addresses bug #887 "ml-dsa: large crate size due to test vectors".

The simplest solution is to exclude all of tests/ in the published crate, so that's what my pull request does.

I think it would be good to just exclude the tests which rely on the large JSON files, i.e. key-gen, sig-gen, and sig-ver

Okay, I'll make those changes.

The other kinda large file is proptests.proptest-regressions (415k). Should I exclude that also?

[tarcieri]

Sure, that's fine

[json420]

Okay, I updated my pull request to exclude the 3 json files. I also excluded their corresponding .rs files, otherwise those tests fail.

Finally, I'm excluding tests/proptests.proptest-regressions. Removing it doesn't seem to cause any test failures.

Thanks!
