Update to numpy>=2

As described in the title; numpy>=2 is required for some projects I am working with, and is becoming the standard in many projects.

Hi @clami66 any thoughts on this? Happy to work to address any concerns.

Thanks!

Until this gets merged, here's how I generate wheels from this branch:

• start from a clean repo state
• add .python-version file with your desired python version
• change pyproject.toml to reflect desired package name and version.
• change run_test.sh to prepend uv run in the binary variables
• run ./run_test.sh
• run uv build
