In the Database constructor, original_directory and original_extension can be given as parameters, but they are not used/stored anywhere: https://gitlab.idiap.ch/bob/bob.db.mobio/blob/master/bob/db/mobio/query.py#L40

What was the plan for these according to the database restructuring? Should these parameters be removed, or should one be able to query the original data from the bob.db database interfaces?
