      This is a convenience method. It is functionally identical to calling
      DataDownloader(ad_manager_client, version, server)
  
      Args:
        [optional]
        version: A string identifying the Ad Manager version to connect to.
            This defaults to what is currently the latest version. This will be
            updated in future releases to point to what is then the
            latest version.
        server: A string identifying the webserver hosting the Ad Manager API.
  
      Returns:
        A DataDownloader tied to this AdManagerClient, ready to download reports.
