Add directory check in save_parquet

[samiravaez]

Added directory existence check in the save_parquet method to ensure the parent directory exists before saving the file. Also, added a test to validate this functionality

Looks great! We'll make sure the tests pass before merging, but should be good to go.

@samiravaez these test failures are not due to your code, but are due to a dependency bug that I fixed on main yesterday. Merge the latest main into your feature branch and re-push to make sure the tests pass.
