vec vs u8

[ckcr4lyf]

We know it's only 6 bytes, don't need vec

Redis performance is indifferent

However, the initial parsing into the [u8; 6] is faster than Vec<u8> :

IP str to bytes/vec     time:   [120.36 ns 123.52 ns 126.92 ns]
IP str to bytes/u8      time:   [32.511 ns 32.607 ns 32.715 ns]
