      Manages tasks in a file system repository. The repository is initialized with the provided task data and supports various actions:
      - 'save': Saves the given task data. If 'id' is not provided in the task data, it will be generated.
      - 'delete': Deletes the task with the specified task ID.
      - 'find_by_id': Finds the task with the specified task ID and returns its data as a dictionary.
      - 'find_by_ids': Finds tasks with the specified list of task IDs and returns their data as a list of dictionaries.
      - 'all_task_data': Finds all tasks and returns their data as a list of dictionaries, sorted by ID in the specified order ('asc' or 'desc').
      - 'task_data': Finds the task with the specified task ID and returns its data as a dictionary, or None if the task is not found.
