Incompatibility with numpy>=2.0

[lazzd]

The library seems not to be compatible with numpy >= 2.0 due to import issues.

Steps to reproduce

When importing the attacks, for example, FoolboxPGDL2:

from secml.adv.attacks import CFoolboxPGDL2

an ImportError is obtained.

ImportError: cannot import name 'NaN' from 'numpy' (/home/lazzaro/miniconda3/envs/secml2/lib/python3.9/site-packages/numpy/__init__.py)

Possible fixes

A possible fix is to install numpy==1.26.4
