Cython 3.2 support

[flying-sheep]

Cython~=3.1.2 means Cython==3.1.*, i.e. I can’t build pyjnius with system libraries since I have Cython 3.2

pyjnius/pyproject.toml

Line 5 in 4aa8be5

"Cython~=3.1.2",

is that intentional or did you mean Cython>=3.1.2

IIRC the motivation was that changing Cython versions can cause builds to fail. Normally the pip makes an appropriate build environment anyway, right?

[flying-sheep]

Not in all situations: e.g. Linux distributions don’t build in venvs, they build with their system-packaged versions of a package

Also Cython 3.1 is (probably already, otherwise soon) unmaintained, meaning bugs will never get fixed

[cmacdonald]

so can you submit a PR that tests Cython (3.1 and) 3.2?

My builds also fail and it's impossible to package this library without hacking out the pyproject.toml.

Please change the dep as suggested.
