 Check the ref-type, before calling _valid() in the Number class.

 - Relaced more goto(ref($x) =~ tr/:/_/rs); with goto($DISPATCH_TAG{ref($x)}); in the Number class. (about ~10-20% faster)

 Added one shared %DISPATCH_TAG hash near the top of the file (right after @SMALL_PRIMES_20), mapping the 5 possible ref() results to their label-safe tags.

 Generalized the Number antidivisor_sigma function, to take an extra argument k, which computes the sum of d**k for all antidivisors d of n.
