pip3 deprecation warning for coming pip23.1 when installing swat

I got this warning when I installed swat today: DEPRECATION: swat 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

I resolved this by installing the wheel package. It seems one of two things is needed: a) update the doc to mention the wheel package as a dependency or b) make the swat install compatible with the coming pip 23.1 release

Thanks for letting me know about this. I'll take a look at it.
