spritz 
This is an implementation of the Spritz spongy RC4-like stream cipher which was documented by Ronald L. Rivest and Jacob C. N. Schuldt.
This implementation is a direct one, based on the pseudocode presented in the
original paper. As such, we make very heavy use of the State monad (and the
lens library to ease our use of it). Future work could (and should) be done to
limit or eliminate our use of State.
The functions provided align with the functions presented in the paper, aside from slight naming and style convention changes.
