COMMON: Split slow and fast CRC implementation
...
They have almost nothing in common. And we probably want to kill slow
implementation anyway now that we have tests

COMMON: Remove the need for most reflecting when initing reflected table
...
Instead reflect the polynomial and change the shifts. Also removes the
need for explicit init.
This makes our crc more similar to its standard implementation

COMMON: Optimize crcFast and related functions.
...
Currently we reflect every byte when working on reflected CRC's. Instead
follow the standard approach of reversing the table and couple of shifts
which is faster
