Efficiently finds and returns an array of the prime factors of a number n. With automatic memoization of Ps. NON-Premium, 30B.

P-finding ("generation" of Primes) adds space and time overhead but it's VERY compensated for lots of reasons. The {y != trunc(y)} is used to ignore perfect squares, because they are composite. The Primality dictionary "Pd" is not essential, but necessary for higher speed
