[feature] Add local file system support

[aaronjheng]

When trying out parseable or doing local development, it would be good to support local FS storage instead of object storage.

hey @aaronjheng thank you for the issue. We do agree, and already added this support with #217. This will be available in the next release (we’re aiming for the release next week)

closing this as fixed by #217
