np.asfarray error due to numpy 2.0.0

[MilanKlausz]

I get the following error when trying to generate plots, due to the new Numpy 2.0.0 release.

stderr: AttributeError: `np.asfarray` was removed in the NumPy 2.0 release. 
Use `np.asarray` with a proper dtype instead.. Did you mean: 'asarray'? 

The script that produces the error is: https://github.com/MilanKlausz/nc_data_lib/blob/main/database/generate_data.py

Based on the full error message below, the issue starts with the plot function called on an NC material, but np.asfarray is used in a couple of places in the NCryastal codebase.

import NCrystal as NC
(...)
self.__mat = NC.load(key)
(...)
self.__mat.plot(do_show=False)

The full error message is the fullowing:

Thanks, this will be fixed in the next release.
