Python-mimeparse

It has been a long time coming since the last release; the project has even been transferred to a different maintainer team during this period.

`python-mimeparse` brings support for CPython 3.13 (by addressing the removal of the `cgi` module), and drops support for Python 3.7. Also included are packaging, tooling, and CI improvements. `python-mimeparse` is otherwise a stable and mature project that hopefully does not need much active development.

Acceptable types can now specify their quality, meaning that if e.g. your resource offers application/json;q=1.0 and text/html;q=0.9, requesting _/_ will return application/json.
