[ASMapNode] Toggle user interaction when liveMap changes (#1753)

Browse Source 
[ASMapNode] Change map snapshot when updating it with a new region (#1754)
[ASMapNode] Commented out code that is causing inaccurate behavior
[ASMapNode] Added the ability to zoom in and show annotations, similar to showAnnotations:animated: of MKMapView.
Added a basic example for ASMapNode to try out the different changes
