Implement deterministic shuffle

[connorkuehl]

std::shuffle is insufficient for the same implementation-defined reasons as why std::default_random_engine is insufficient.

On the revision, Module::createRNG was mentioned which may be applicable here, but not code complete as they suggest some of its patches are still floating around on Phabricator.

I think it's only the overloaded version of std::shuffle which does not receive a PRNG is implementation-defined.

See https://en.cppreference.com/w/cpp/algorithm/random_shuffle

I could be wrong though...
