AtomicSaver and iter find files crash when given a pathlib.Path argument

AtomicSaver and iter find files crash when given a pathlib.Path argument: a task in Repo2RLEnv R2E-Gym / SWEGEN (Harbor dataset). Both AtomicSaver and iter find files in boltons.fileutils fail when passed a pathlib.Path (or any os.PathLike ) instead of a plain string path.
