setTrafficIncidentsEnabled
Enables or disables visualization of on-route traffic incidents.
This function can be called at any moment of the RoutingVisualization lifecycle. For example, if it is called when no traffic incidents are available (e.g., before displaying a route plan), the new visibility status (either enabled or disabled) is saved and applied later when traffic incidents are available. If it is called when traffic incidents are available (e.g., during the route planning phase), the new status takes effect immediately on the traffic incidents.
