…ptional dependencies still lack compat

An aspect I hadn't considered earlier is that some packages may have dropped support for Python 3.9 before adding compatibility with numpy 2.0, in which case a brand new env in Python 3.9 may be broken. I'm not going to worry about that right now but it's something to keep in mind if CI breaks specifically on 3.9 even after all our optional dependencies have a numpy2-compatible release. update 16-05-2024: this was debated on numpy's mailing list so hopefully awareness of this problem is higher now. |

My understanding is that netcdf4 maintainers do not wish to build off of a numpy release candidate and are waiting for the final stable release, but the dev branch is already compatible, so I don't expect it to be a blocker for long. |

PR Summary
This PR isn't meant to be merged
I've been watching numpy/numpy#26191
At the time I'm opening this, all our core dependencies (matplotlib, unyt, ewah-bool-utils) already have compatible releases.
This will unleash full CI with numpy 2 at runtime to reveal which of our optional and transitional dependencies still lack support for it, so I have a chance to reach out to them before the final release drops.
This table may be incomplete, but CI doesn't forgive, which is why this is a PR and not an issue.
