numpy.float128 missing

[mrava87]

Looks like tests are failing (https://github.com/PyLops/pylops-mpi/actions/runs/9237403210/job/25414331862?pr=100) because:

/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/numpy/__init__.py:333: in __getattr__
    raise AttributeError("module {!r} has no attribute "
E   AttributeError: module 'numpy' has no attribute 'float128'. Did you mean: 'float16'?

I see that numpy-1.26.4 was installed. I tried doing the same in Colab and I do not have any problem, I worry this may be a macos thing as these are the actions that failed (others just stopped...)

Anyhow, perhaps we should downcast everything to just float64/complex128 as we mostly do in pylops too? Or we would need to catch the os and based on that choose what to use (but I am not sure it is worth the effort for float128 that is hardly used in real life - in many applications float32 is more than enough 😃
