numpy 2.0 support

[pllim]

Currently devdeps does not use numpy 2.0.dev nightly wheel. Not sure if I can get to this before numpy 2.0 is released for real next month. We'll find out for sure when it is released and CI starts to fail. 😬

I think in numpy 2, something got "upgraded" from int to float, maybe, or could be uint and int cannot be bitwise like that anymore.
