Python 3.9 has been out of extended support for over half a year now. Removing support for it will allow us to finally update some crucial dependencies (like pyo3 and numpy) to recent versions. This commit removes Python 3.9 support from `pyproject.toml` and from CI, and updates the `pyo3` and `numpy` dependencies in `Cargo.toml` to the respective latest versions. All rust and python tests pass (tested with python python 3.12.11) but there are some compilation warnings.

Involves minor fixes to the rust code to make it compatible with the latest versions of the dependencies, and to resolve all clippy lints.

The updated dependency `hashbrown` requires `edition2024`, which wasn't stabilized until rust 1.85 (released Feb 20, 2025). This is a breaking change and will thus require bumping the leading component of the version number.
We increased MSRV, which I consider a breaking change, thus the bump in leading version number.
