Attribute error when using numpy v1.24 due to deprecation of np.bool

[oradwastaken]

In numpy 1.20, the np.bool type was deprecated in favour of the built in bool type. np.bool was finally removed in v.1.24. I recently installed meep on a new machine, and I guess it pulled the latest version of numpy, and when running my simulations the following error was raised:

AttributeError: module 'numpy' has no attribute 'bool'. Did you mean: 'bool_'?

This seems to only happen when I run my simulation using MPI, even with only one core. It seems the mp.merge_subgroup_data() command is what's causing the issue. This error is raised with any version of python I've tried (3.9, 3.10, 3.11) and any version of meep (1.23, 1.24, 1.25).

Below are the relevant parts of the traceback:

J_out = mp.merge_subgroup_data(J_out)

This error was fixed in #2349. See also #2353 for the list of changes that were recently made to support Numpy 1.24.

You will therefore need to build Meep from source or wait until the next release of the Conda package with version 1.26.

Ah, thanks for the quick reply! I searched for this in the issues but I think I just looked for open issues.
