pypi don't have py3.9 whl release and tar.gz with source code

[betterlch]

Hi, here is some small problams:

1. pypi don't have cp3.9 whl release.
2. pypi don't have tar.gz with source code for build. (so build from git clone maybe better)

Thanks for your time.

Also, releases of v0.5 and v0.6 on github are missing

Hello. I confirm that there are sdist releases on PYPI, so if your platform is not the one the release wheel (and given there few wheels, it will happen to a lot of people), you just can't install recent version of python-hyperscan. Enabling and pushing the sdist to PYPI should be a breeze. Could this be done, @darvid? Thank you in advance 🙏
