Numpy deprecation of np.float_

[xQiratNL]

Hi @ThomasTNO,

I was recently using this library as an example for a course lab, but noticed that Numpy has deprecated np.float_ since reaching version 2.0.

Since numpy is not version constrained this gave an error, due to its usage here:

mpyc.secure_learning/tno/mpc/mpyc/secure_learning/utils/types.py

Line 26 in 4062358

NumpyFloatArray = npt.NDArray[np.float_]

It should probably be fine to replace it by np.float64, which is the recommended fix, and probably you may want to restrict the numpy version :)

Steps to reproduce: install this library in a fresh environment and run one of the example.

Hi @xQiratNL,

Thanks for noting. Internally this was fixed already. I am working on making the latest versions available asap.
