MapMoveAttribution mixin
Remembers camera updates the app asked for, so the widget layer can tell them apart from user gestures.
Google Maps and the Mapbox SDK report that the camera moved and nothing about why, so the only way to attribute a move is to remember having asked for it. Controllers mix this in and call beginProgrammaticMove before issuing a camera update; the widget reads moveSource as each camera event arrives and calls onCameraSettled when the camera comes to rest.
flutter_map reports a source of its own (MapEventSource) and needs none
of this.
