Add external vector tiles

Add vector map tiles from an external source, using the {z}/{x}/{y} URL scheme.

import MapboxMaps

final class ViewController: UIViewController {
private var mapView: MapView!

// property on `VectorSource` to set the URL.

}

// Define the layer's positioning within the layer stack so
// that it doesn't obscure other important labels.
