Refactoring for numpy >2.0 support

[maestroque]

Currently the numpy package is constrained to be <2, due to some incompatibilities within the codebase and the new API. The ones currently detected include:

A workaround shall be found for compatibility with versions both over and under numpy 2.0. Some relevant PRs could be these [1] [2]

[Note] Edit this issue accordingly if other incompatibilities are found
