Typing request: accept `pathlib.Path`s as parameters for get_evaluable_architecture

[Lenormju]

The typing indicates that str are expected for root_path and module_path parameters. But they get converted to Path after. Could you change the typing to be an union str | Path so that the round-trip is not needed ? No other change is required, because Path(something_that_is_already_a_pathlib_path) is a no-op.
