missing.

Skips the 0 major version.
* Add missing changes from refactor

* Add test case with path requiring fsspec
* Avoid writing logs to file unless output_path is local
* Document the possibility of using paths supported by fsspec
* Fix style and lint
* Add missing lint fixes
* Add type annotations to new functions
