A few suggestions:

1. Drop Python 3.7 from the test suite and no longer explicitly support it since it's at EOL
2. Add support for Python 3.11 to the test suite (and 3.12 if it happens to work...)
3. Add requires-python, e.g. requires-python = ">=3.8, <3.12" to the setup.py (plus the corresponding classifiers) to clearly mark what versions are supported by cclib
