Pipeline the calculation

Pipeline the calculation of the hash value to allow for longer message lengths and allow for easier integration into real systems.

This would be likely be pretty difficult due to the dependency on 64 iterations of the compression cycle being run between 512 bit messages being used in the hashing algorithm.

On second thought, if you were to expand the compression state cycles to each being their own pipeline cycle you could think of the module as having up to 64 time multiplexed slots and this would be able to work with message lengths exceeding 512 bits assuming the hash calculated for each 512 bit message wrapped back to the input of the pipeline.
