Fuzz testing for HashX. Uses a hook into the pseudorandom number
stream to test the program generator deeply on input that can
be mutated by the fuzzer. Confirms program generation by running
a small number of arbitrary test hashes, so we don't need to
understand the implementation-specific program format to test the
program generator.
We test four implementations in parallel this way, the compiled and
interpreted implementations included in both this crate and c-tor.
