Versions of numpy starting in 2.X will fail due to bool8 data-type being removed

#Support for seven data type string aliases has been removed from np.dtype: int0, uint0, void0, object0, str0, bytes0 and bool8.

Looks like this is not directly a voxcell issue but maybe capping the numpy version can help prevent this problem?

Capping the numpy would be dangerous, since it impacts the resolver, and it's not really a hard dependency.

@eleftherioszisis successfully got pynrrd to drop it, so once that's released, we should be in the clear: mhe/pynrrd#154

[ssssarah]

Cool, indeed it's much better. Thanks!

[mgeplf]

We'll have to see when a release is made, perhaps I will ping the maintainer.

[mgeplf]

A release has been made, so nptyping isn't used, and this error will go away.
However, their API has changed, so we have another thing to fix: #37
