Interop is not compatible with Numpy 2.0.0

[Aratz]

Numpy 2.0.0 was released a few weeks ago and it breaks interop.

Steps to reproduce

1. With python 3.10, run pip install interop
2. Test the installation: python -m interop --test

Expected results

the tests pass

Actual results

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.0 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Proposed solution

As suggested in the error message, numpy should be pinned in the installation script, or interop should be made compatible with numpy 2.0
