migration to numpy>=2.0

[clausmichele]

I started checking how to migrate to the latest numpy version. I'm following the official migration guide.

First step - check what we need to modify:

$ ruff openeo_processes_dask/process_implementations/ --select NPY201
warning: `ruff <path>` is deprecated. Use `ruff check <path>` instead.
openeo_processes_dask/process_implementations/comparison.py:29:8: NPY201 [*] `np.issubsctype` will be removed in NumPy 2.0. Use `numpy.issubdtype` instead.

Blocking stone: dask-geopandas doesn't support numpy>2.0, since it depends on pyarrow which again doesn't support yet numpy>2.0.

Thanks for investigating! For now, I added the numpy<2.0 dependency to the pyproject.toml as suggested here: #310 (just for reference)
