Base Set Exchange URL should use HTTPS

[gayverjr]

Hello,
It appears that fetching from the Basis Set Exchange is currently broken because the service has deprecated/redirected its HTTP endpoints in favor of HTTPS.

When I run example.py, I'm currently getting this error on line 39:

    coordinates, weights = numgrid.atom_grid_bse(
                           ^^^^^^^^^^^^^^^^^^^^^^
pyo3_runtime.PanicException: called `Result::unwrap()` on an `Err` value: reqwest::Error { kind: Request, url: "http://basissetexchange.org/api/basis/cc-pVDZ/format/json?elements=8", source: hyper_util::client::legacy::Error(Connect, ConnectError("invalid URL, scheme is not http")) }

I think all that needs to be done is to update this line in bse.rs to use HTTPS.

Thanks for notifying me about it. I will update the code as soon as possible.

I will try to fix it tomorrow. I want to package for Python 3.14 and update dependencies at the same time and also the CI will need some upkeep so it's more than 10 minutes.
