Update tests filer

- Replace [fs](https://pypi.org/project/fs/) by [fsspec](https://pypi.org/project/fsspec/)
because of deprecation of [pkg_resource](https://setuptools.pypa.io/en/latest/history.html#deprecations-and-removals)
starting pyhton>3.12 from Setuptools to fix CI/CD.
- Update `test_filer.py` to use `fsspec`
