publish a wheel

I notice that this package publishes only source distributions, so that every user has to build the wheel themselves. Better for package owners to build and publish wheels once and for all.

I did not find a workflow in this repository for publishing or I would have submitted a pull request. If you are doing this manually a typical workflow would be something like
```
python -m pip install build twine
python -m build
twine upload dist/*
```

Start by checking the repository's release workflows and package build metadata. Use the reported python -m build and twine upload dist/* flow as the reference; done means a wheel is built and published alongside the source distribution, so users no longer need to build it themselves.
