Because Numpy 2.x shared libraries are ABI compatible back to Numpy 1.x, this requires a newer build environment to produce the Python bindings, but the resulting library is backwards compatible. (This is ideal for a wheel-based flow.)

@ketiltrout and @arahlin, sorry to drop this on you before the holidays. This is a precursor to #21. |

I think the footprint of this PR is relatively small and otherwise simplifies python wheels and forward compatibility a great deal. |

This PR shifts the Python bindings from the Numpy 1.x to Numpy 2.x API. See the following for context:
https://numpy.org/doc/stable/numpy_2_0_migration_guide.html
https://numpy.org/doc/2.0/dev/depending_on_numpy.html
Numpy 2.x is now a better choice than 1.x for modules:
It makes sense to shift getdata in the same direction too. Along the way, I've refreshed the wheel build (to repair deprecated MacOS builders, to enable Python 3.13, and to deprecate 3.8.)
Comments welcome. While the build succeeds and regression tests pass, I have not used these code "in anger". I do plan to follow up this PR with a wheel builder for Windows, and think Numpy 2.x is a better basis for this work.
