class_docstr: Streaming gzip decompressor.
  
  The interface is like that of `zlib.decompressobj` (without some of the
  optional arguments, but it understands gzip headers and checksums.
docstr: 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.
