Optimizations

[05nelsonm]

This December I have been highly focused on performance optimizations. I am happy to announce that as of KotlinCrypto.hash version 0.5.6, things are now bench-marking on par or better than Bouncy Castle for JVM.

Releases 0.5.4, 0.5.5, and finally 0.5.6 have all been optimization based fixes. Here's the breakdown:
