Subject: TomTom: Add method for `calculateRoute` endpoint

A new method to provide access to the `/calculateRoute` endpoint, which
calculates costs for a single route through a bunch of waypoints.

This doesn't work currently because the API requires that I send
`supportingPoints` in the body of the request. Since I'm not too clear
on what those are, I'm going to cut off development of this method here
and just use `#batch` instead for my purposes.

My idea was to use this endpoint instead of `/batch` to allow us to
calculate a single route instead of having the API do `/calculateRoute`
for each of our point pairs. This seemed like it would be more
efficient, and give us our distance and time costs between each waypoint
all in one go, but since I'm not clear on how to use this API and
whether it will give us the correct data, I'm going to stick with
`/batch`. I'll probably be reverting this code. Just committing it now
in case it becomes useful in the future.
