Enhance factorized with Quadratic Sieve.

[neizod]

factorized function should became a class, which has some of this features:

• factor in lazy manner (returns an iterator, or some chaining objects like linked list).
• any number should use trial_division algorithm to factoring, until reach some point that factor using this algorithm slow.
• put remaining number test for primality, if turns out composite, use quadratic_sieve to continue factor it.
