pyscript capability

I'm starting a dedicated thread here:

I am getting an error when I import caeroc directly.
Its about `Can't find a pure Python 3 wheel for: 'numpy<2,>=1.21'`

I think this is defined in the caeroc packaging:
- pyproject.toml in the dependencies section.
- also in uv.lock where the version 1.2.6 is specifically mentioned
- Alas I have no idea how uv.lock works... :(

I am not sure why pyodide is not handling it but I wonder if there is a way to specifiy it so we can get it to work.
- perhaps pick a specific numpy version that pyodide has a version for,
- or possibly move to numpy 2 ?
- Here is the migration guide. https://numpy.org/devdocs/numpy_2_0_migration_guide.html
- https://www.datacamp.com/tutorial/numpy-2-release

Start by reproducing the direct caeroc import error, then inspect the dependency sections in pyproject.toml and the numpy entry in uv.lock. Check which numpy version is available as a pure Python 3 wheel for the Pyodide environment and update the packaging metadata accordingly. Done means direct import no longer fails because of the numpy dependency.
