Add numpy to dependencies including version

[crlna16]

The numpy version (2.0) that was installed with pip install ai-models was not compatible with the other libraries. Downgrading to version 1.26 fixed that for me. I would suggest to add numpy explicitly with a version 1.x to the dependencies until the libraries adapt to numpy 2.x

Seconding this. While some of the models work out of the box with Numpy 2.0, models such as FCNv2 (ai-models-fourcastnetv2) break from an import change (numpy v1.x: from numpy.lib.arraypad import pad numpy v2.x: from numpy import pad).
