replace np.in1d with np.isin

[candytaco]

in1d was deprecated in numpy 2.0 in favor of isin and removed in numpy 2.4.0.

Also updated requirements.txt and pypoject.toml to specify numpy>=1.13.0, when isin was first introduced.

Code Review

This pull request replaces the deprecated np.in1d function with np.isin across several modules and updates the project's dependencies to require NumPy 1.13.0 or higher. The review feedback correctly identifies opportunities to simplify the code by removing redundant .reshape() and .flatten() calls, as np.isin preserves the shape of the input array unlike its predecessor.
