np.complex was a deprecated

When I'm doing python precompute_conversion.py it gives me the following error:

`np.complex` was a deprecated alias for the builtin `complex`. To avoid this error in existing code, use `complex` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.complex128` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'complex_'?

The source is a clone of the current main branch.

How do I resolve this?

It looks like recent versions of colour-science resolve this (e.g. 0.4.3) but are not yet marked as available for python 3.12

Can you try reinstalling dependencies using python 3.11 and confirm whether you are still seeing this? e.g. I did the following in a fresh clone of the repo:

% python3.11 -m venv venv
% source venv/bin/activate  # not sure what is the requivalent on windows
% pip install -r requirements.txt
% python3.11 precompute_conversion.py
Precomputing conversion matrix from 24-bit RGB to CAM16UCS colour space
Precomputing conversion matrix from 12-bit //gs RGB to CAM16UCS colour space

It works now. Thanks @KrisKennaway !
