Enhancement: Display arrival time for all options - and maybe arrival time within elevation profile info window

#### Enhancement:
- Display the arrival time in the UI.

#### Use Case:
- As a user, I would like a computer to do the time math for when I will arrive at my destination instead of the user doing the math every time they find a route.

#### What to change:
- See screenshot
- Update the UI to show the actual anticipated arrival time of the route in the list of route options and possibly by a hovering info window over the route. A hovering window over the route is a great UI way to identify the route you are assessing instead of having to click on each one to identify it.
- Show the arrival time as well in the Elevation profile UI, if it exists. This is nice to just see what time you will arrive in a specific town X miles into your trip. Might be tough to get the origin and destination's timezone from a geocoder to do the difference calculation. Note: the origin timezone might not be the user's computer's device time.
- Make sure to take into account origin AND destination timezone differences.

#### Am I willing to tackle this?
- Yes, but not for at least a couple months timing-wise.

#### Future Ideas:
- Implement `Leave Now`, `Depart at: `, `Arrive by: `
- Show the arrival time as well in the Elevation profile UI
