StorageDownloadTask implements resumable downloads from an object in Firebase Storage.

Downloads can be returned on completion with a completion handler, and can be monitored by attaching observers, or controlled by calling pause(), resume(), or cancel().

Downloads can currently be returned as Data in memory, or as a URL to a file on disk.

Downloads are performed on a background queue, and callbacks are raised on the developer specified callbackQueue in Storage, or the main queue if left unspecified.
