setRoutes
Set a list of routes.
If the list is not empty, the route at index 0 is valid, and the trip session is started, then the SDK enters an Active Guidance
state and RouteProgress updates will be available.
If the list is empty, the SDK will exit the Active Guidance
state.
Use RoutesObserver and MapboxNavigation.registerRoutesObserver to observe whenever the routes list reference managed by the SDK changes, regardless of a source.
