`StridedMemoryView` constructor tests fail with `TypeError`

For some reason this is not caught by our CI 🤔 I need to look into what's missing in our CI tomorrow... @cpcloud could you take a look?

Sorry I missed the ping, taking a look now.

The problem here was that s.handle from the test returns a CUstream, while the from_cuda_array_interface API accepts int (or None).

In Cython 3.2, automatic conversion of objects implementing __float__ and __int__ (whose existence will cause the C API PyNumber_Check to return true) was added in cython/cython#6808, which allows the current test suite to pass.

Your Cython version was out of date (3.1.3 from the env list you sent me). We require a minimum of Cython 3.2 per the pyproject.toml.
