Updates Flights model to support roundtrips/return trips.
Changes
Wrote additional tests to cover areas we weren't testing
Changed model to handle return trips for distance + duration by multiplying footprint
Changed model to handle return trips with airport codes by reversing and running calculations again (since the direction matters due to loadfactors, etc.)
cc @martincollignon - the calculation does actually differ based on direction already, so the model now supports that (so we in future can add wind-data and more awesome things 😎)
