Bump-up version of cibuildwheel to support Python3.14

[mstarecek]

Using newer version of cibuildwheel will generate wheels also for Python3.14
This should also solve issue #28

I've performed basic tests on Windows. Could maintainers pls run Linux and Mac?

it would also be lovely if this package could be built for 3.13t and 3.14t (the free-threaded builds).

i've tried locally, and they seem to build fine.

uv venv --python 3.13t
source ./venv/bin/activate
pip install .

for cibuildwheel, it looks like this would require setting the "enable" flag to "cpython-freethreading":
