Switch to scikit-build-core, build wheels with bundled OpenBLAS

Fixes gh-164

this will need a version bump - 0.6.2? Will wait for review comments before pushing any changes.

When distributing wheels that vendor binary dependencies, you'll need to package the dependencies' licenses as per each dependency's license terms. I think there is some standard tool to help manage this (as it has been solved for SciPy and others).

Thanks, I'll look into this.

SLICOT is also differently licensed to Slycot (MIT vs GPL), I suppose we should indicate that somewhere too.
