Sort output for repeatability
Sort output for repeatability

The ordering of a hash can't be guaranteed, however the output doesn't
specifically need to be a hash; it needs to show the prime factors and their
multiplicity which is still guaranteed.  However now we have repeatability
and thus testability.
