add a wheel to pypi in addition to a tar.gz file

[shapiromatron]

Got an install warning:

DEPRECATION: forestplot is being installed using the legacy 'setup.py install' method, 
because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 
23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-
pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

It would be good to also push wheels to pypi; since this package is pure python it should be fairly straightforward. I would be happy to contribute to a PR if you would accept.

@shapiromatron thanks for raising this issue.
Is this what you get after doing a pip install forestplot?

I don't seem to be getting this error. Let me investigate a little too.

Yes, but I didn't have the wheel package installed. It think when you make a release, you'll want to build a wheel in addition to a tar.gz. I think you just need to add bdist_wheel to this line:

forestplot/Makefile

Line 32 in 925f4a1

@python setup.py sdist

Can you make a PR for this?
But I'm not sure whether we should merge with main or patch. I'm making some changes for the next version from patch.
