Travis CI: Test on Python 3.13 beta

cclauss · ahupp · commit 8eecfb78bfa0 · 2024-05-14T22:33:51.000-07:00
The Python 3.13 release notes mention `python-magic` as one of the alternatives for `imghdr` which was removed from the Standard Library so let's ensure that its tests pass on Python 3.13 beta. https://www.python.org/downloads/release/python-3130b1/ May raise `ModuleNotFoundError: No module named 'imghdr'` because Python 3.13 removes it from the Standard Library. * https://docs.python.org/3/library/imghdr.html > imghdr: use the projects [filetype](https://pypi.org/project/filetype/), [puremagic](https://pypi.org/project/puremagic/), or [python-magic](https://pypi.org/project/python-magic/) instead.
