Separate change from what is in the description?

There is a test for twitter.com in this file, and it responds with a deflate
encoded body. So I can make the test pass by moving the EndOfStream flag to the
HeaderFrame and add decoding support for deflate.

+    stream = stream.transform(ZLIB.decoder);
   }
   return await stream.transform(UTF8.decoder).join('');
 }
