Remove references to deprecated NumPy type aliases

This change replaces references to a number of deprecated NumPy type
aliases (np.bool, np.int, np.float, np.complex, np.object, np.str)
with their recommended replacement
(bool, int, float, complex, object, str).

NumPy 1.24 drops the deprecated aliases
so we must remove uses before updating NumPy.
