Norman Maurer e177b74874 Use ByteProcessor in HpackHuffmanDecoder to reduce bound-checks and r… (#9317) 
Motivation:

ff0045e3e1 changed HpackHuffmanDecoder to use a lookup-table which greatly improved performance. We can squeeze out another 3% win by using an ByteProcessor which will reduce the number of bound-checks / reference-count-checks needed by processing byte-by-byte.

Modifications:

Implement logic with ByteProcessor

Result:

Another ~3% perf improvement which shows up when using h2load to simulate load.

`h2load -c 100 -m 100 --duration 60 --warm-up-time 10 http://127.0.0.1:8080`
