Various changes (#96)

* Improve some error messages by including the string value of the path so it is clear what failed.
* Cleaned up notebook for clarity and brevity, also added table of fsspec supported filesystems.
* Fixed bug causing incorrect rglob results (top level glob matches were not included).
* GitHub Actions: Only run on PRs and pushes to main and tagged commits, to fix duplicate runs.
* GitHub Actions: Don't fail fast, so that multiple failures can be reviewed after each run.
* GitHub Actions: Run on "3.11" rather than "3.11-dev".
