------------------
* Update Python support to 3.5-3.8, as 3.4 has reached its end of life.
* Converted setuptools metadata to configuration file. This meant removing the
``__version__`` attribute from the package. If you want to inspect the
installed version, use
``importlib.metadata.version("pytest-super-check")``
(`docs <https://docs.python.org/3.8/library/importlib.metadata.html#distribution-versions>`__ /
`backport <https://pypi.org/project/importlib-metadata/>`__).
