Improve the hash rate of the Hash function

[dkrutsko]

Currently, the Hash class has abysmal performance when compared to other CRC32 algorithms. Looking at our options here, here and here, it's clear that there's a lot of improvements which could be made. Read the table below to see how we compare (Ignore the differences in the result as the comparison uses the iSCSI/Castagnoli polynomial where as we use the Ethernet/ZIP one).
