Feat: Allows specifying a weight function for individual ranges for the Connected Ranges collector

[Christopher-Chianelli]

Is your feature request related to a problem? Please describe.
Sometimes a Job requires multiple of the same resource. For instance, a Job might require either 2 or 3 forklifts.
If there are a limited number of forklifts, then schedules where the number of required forklifts at any given time is over the limit is infeasible.

The Connected Range collector is useful when the Job will always require 1 forklift, but cannot handle cases where each Job require a different number of forklifts.

Describe the solution you'd like
The connected ranges collector takes an optional weighting function parameter from range to int (defaulting to range -> 1).
For instance,

toConnectedTemporalRanges(Job::getStart, Job::getEnd, Job::getRequiredForkliftCount)
