Import splitmix-0.0.3

Pure Haskell implementation of SplitMix described in

Guy L. Steele, Jr., Doug Lea, and Christine H. Flood. 2014. Fast
splittable pseudorandom number generators. In Proceedings of the 2014
ACM International Conference on Object Oriented Programming Systems
Languages & Applications (OOPSLA '14). ACM, New York, NY, USA,
453-472. DOI: https://doi.org/10.1145/2660193.2660195

The paper describes a new algorithm SplitMix for splittable
pseudorandom number generator that is quite fast: 9 64 bit
arithmetic/logical operations per 64 bits generated.

SplitMix is tested with two standard statistical test suites
(DieHarder and TestU01, this implementation only using the former) and
it appears to be adequate for "everyday" use, such as Monte Carlo
algorithms and randomized data structures where speed is important.

In particular, it should not be used for cryptographic or security
applications, because generated sequences of pseudorandom values are
too predictable (the mixing functions are easily inverted, and two
successive outputs suffice to reconstruct the internal state).
