Fix Scoping.ids setter for int64 arrays

[PProfizi]

Closes #2037

Edit: this fixes the issue for np.ndarray(dtype=int64) which is the new default, however for some reason the case:

from ansys.dpf import core as dpf
import numpy as np

nids = np.array([1,2,3,4],dtype=int)
nids = list(nids)
print(nids)
scop = dpf.Scoping(ids=nids, location= dpf.locations.nodal)
print(nids)
print(scop.ids)

already worked despite the list being:
[np.int64(1), np.int64(2), np.int64(3), np.int64(4)]

Why would this case work? In theory these too would need to be converted to int32.
