Decompress a chunk, returning newly-available data.

        Some data may be buffered for later processing; `flush` must
        be called when there is no more input data to ensure that
        all data was processed.

        If ``max_length`` is given, some input data may be left over
        in ``unconsumed_tail``; you must retrieve this value and pass
        it back to a future call to `decompress` if it is not empty.
