Support for numpy >= 2.0.2

[envelio-cb]

I am working on upgrading our ecosystem to use numpy >= 2.0.2 which currently breaks at your package.

Afaik you don't use numpy in your code except for testing. Thus, I am wondering if you can either drop the dependency and add it as dev-only dependency or if you can be less strict in the versioning of numpy and support numpy >= 2.0.2.

Here is also a list of the numpy ecosystem compatibility with numpy 2.0: https://github.com/numpy/numpy/issues/26191

Kind regards
