Numpy 2.x compatibility

[greschd]

What is the status of PyDPF w.r.t. compatibility with the numpy 2.x release? I have noticed that it is declared as numpy<2, but don't know whether there is a known incompatibility, or it is simply a conservative dependency declaration.

The reason I stumbled upon this is that the poetry dependency solver in PyACP (which does not restrict numpy):

• upgraded numpy to 2.x
• downgraded DPF core to 0.12.2, which does not limit numpy (but presumably isn't any more compatible)

By forcing ansys-dpf-core>=0.13, I could get it to pick the older numpy and newer DPF instead.
