Move to pyproject.toml instead of setup.py for packaging #147
Description
When installing parse with a recent version of Pip, I get the following warning:
DEPRECATION: parse 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.

@r1chardj0n3s Would you be interested in a PR moving to a "modern" build system? I can also update the tests and classifiers so that they run on the currently supported Python versions: 3.7 to 3.11
