xarray-sql is slow to install with `uv` in a new python environment on an M1 mac

When I uv add xarray-sql -v to a clean Python project managed by uv on my M1 mac, it seems to trigger a local compilation of the sources with rust:

I think a remedy for this would be to pre-compile and distribute binaries for ARM mac (I thought these already existed).
