TomTom::Matrix#extract_costs_to_way_costs!: Try to include stop IDs

Change this code to get stop IDs based on the change in
be3e1effcdea87909a181c7e9b12cf6867b1839d. It should use these IDs to
construct new `WayCost`s with the combination of stop IDs from departure
and arrival stops.

This doesn't work currently because the method has code that tries to
index the `points` collection, but it's a `Set`, and sets don't support
indexing and aren't ordered, so this code errors. Need to change the
`Set` to something else that will work here.
