MHKiT Python 3.12 support

[ssolson]

Adds Python 3.12 as a supported version.

Required installing setup tools for pip installs due to hypyd. This has been fixed but not released to pypi yet:
HDFGroup/h5pyd#169
Once a new release of h5pyd to pypi happens we should remove this step.

Thanks @ssolson

Is setuptools only required for the test environment or for MHKiT generally using Python 3.12? If the former, let's merge this now. If the latter, let's wait until our next release is closer and see if h5pyd has this fix on pypi then

It is the latter, however, as this is the development branch I think developing all PRs for 3.12 support now would be beneficial rather than trying to fix any potential issues later.

I want to wait on #333 to be merged before this PR.

Fair point, that makes sense to avoid a bunch of urgent bugfixes right before we want to tag a release. Understood on timing this relative to #333. Tests pass on 3.12.

I successfully created a 3.12 environment with MHKiT locally, but FYI I did get a pip deprecation warning when using the editable install (pip install -e .) This method will not be supported in pip>=25.0 and will require another method. Not a chance required in this PR, but will be an upcoming issue in the future.
