Optimize Journey::Route#score
Scoring routes based on constraints repeated many type conversions that
could be performed in the outer loop. Determinations of score and
fitness also used Array operations that required allocations. Against
my benchmark with a large routeset, this reduced object allocations by
over 30x and wall time by over 3x.
