 A stream that is reset might have multiple outstanding header blocks.  A decoder
-that receives a stream reset before the end of a stream generates a Stream Reset
-Acknowledgment instruction on the decoder stream.  This signals to the encoder
-that any references to the dynamic table are no longer outstanding.

 An encoder cannot infer from this acknowledgement that any dynamic table entries
 referenced have been received.
 
 The instruction begins with the '11' two-bit pattern. The instruction includes
