49bf0db8fd SHAKE: Don't use function pointers (#20)
* xorIn and copyOut function pointers cause input and output data
  to be moved to heap. This degrades performance of calling code.

* This change removes usage of those function pointers. We will always
  use unaligned implementation as it's faster (but may crash on some
  systems)

* Benchmark compares generic vs unaligned xorIn and copyOut
