Now autoupdates with ObservableObject

the @SyncedWatchState property wrapper can now be used directly in an ObservableObject without any additional setup. This will now call objectWilLChange.send() on the enclosing ObservableObject instance whenever it's value is changed to trigger a UI render in SwiftUI.
