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":

https://cibuildwheel.pypa.io/en/stable/options/#enable

- name: Build wheels
  uses: pypa/cibuildwheel@v3.3.1
  with:
    enable: cpython-freethreading

Hi Maintainers, any news regarding the Python 3.14 wheels? Thanks

Hello Maintainers, could you please pay attention for this issue ? It helps to move with other projects to Python 3.14 (Pi :-))

It would be great if we could get 3.14 support checked in here!

@Salamist @flit: It would be great to have support for Python 3.14. Could you have a look at this PR?
@mstarecek: I think it would make sense to bump cibuildwheel to the latest version v3.4.1 since this PR has been sitting for a while, right?
