bdcdcdea7d Optimize chunker 
Skip MinSize bytes at the beginning of each chunk. This increases
throughput about 30% percent.

Before:
    $ go test -v -bench . ./chunker
    === RUN TestChunker
    --- PASS: TestChunker (0.60s)
    === RUN TestChunkerReuse
    --- PASS: TestChunkerReuse (2.18s)
    PASS
