Numpy 2.0 compatibility

The current main error that numpy 2 seems to cause:

ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Solution here is likely to wait for p4p (and possibly other upstream libraries) to be recompiled against numpy 2.0
