 - Change the order of advected points returned by `DryAdvection` to be consistent with the input order at each time step.
 - Add the `RUF` ruleset for linting and formatting the codebase.
 - Update type hints for `numpy` 2.2 compatibility. Additional changes may be required after the next iteration of the `numpy` 2.2 series.
