Provide Python wheels

[BSchilperoort]

I tried using bmipy for a teachbooks BMI "toybox". However, micropip can only install packages with pure python wheels, but only the source tarball is available for bmipy.

Apart from enabling easy installation in WASM Python, having wheels available has more benefits:

1. Faster installation for pure Python packages.
2. Avoids arbitrary code execution for installation. (Avoids setup.py)
3. Allows better caching for testing and continuous integration.
4. Creates .pyc files as part of installation to ensure they match the Python interpreter used.
5. More consistent installs across platforms and machines.

To create both a tarball and wheel, the command following command suffices:

> python -m build 
...
Successfully built bmipy-2.0.2.dev0.tar.gz and bmipy-2.0.2.dev0-py3-none-any.whl

Note that this should not require a new release: It is possible to publish new artifacts that are more specific for a given release.

@mcflugen has set up a job in the Landlab CI to build wheels. Perhaps this could be adapted for use here?

Yup, this would be easy to do. In fact, we already have a nox session that builds wheels (nox -s build).
