nptyping dependency is troubled

[0-wiz-0]

nptyping hasn't been updated for numpy 2, which makes the self tests fail with:

tests/test_sphinx_autodoc_typehints.py:54: in <module>
    import nptyping
/usr/pkg/lib/python3.12/site-packages/nptyping/__init__.py:32: in <module>
    from nptyping.ndarray import NDArray
/usr/pkg/lib/python3.12/site-packages/nptyping/ndarray.py:40: in <module>
    from nptyping.shape import Shape
/usr/pkg/lib/python3.12/site-packages/nptyping/shape.py:29: in <module>
    from nptyping.shape_expression import (
/usr/pkg/lib/python3.12/site-packages/nptyping/shape_expression.py:36: in <module>
    from nptyping.typing_ import ShapeExpression, ShapeTuple
/usr/pkg/lib/python3.12/site-packages/nptyping/typing_.py:51: in <module>
    Bool8 = np.bool8
/usr/pkg/lib/python3.12/site-packages/numpy/__init__.py:414: in __getattr__
    raise AttributeError("module {!r} has no attribute "
E   AttributeError: module 'numpy' has no attribute 'bool8'. Did you mean: 'bool'?

There's a bug report open at nptyping in ramonhagenaars/nptyping#124 with no reply.
At least one other project has switched to numpy.typing: mhe/pynrrd#154
