Supports AnimatedImage animation control using of SwiftUI Binding

[dreampiggy]

Add support for Animation Control of AnimatedImage !

This feature is really useful for animation, like something logic to stop animation when doing transition or hover. It's quite common in iOS App.

This API design use the Binding of SwiftUI. I reference the built-in View like Toggle and Sheet. Which make it easy for user to use (Just one line of code)

@State var isAnimating: Bool = true // I just need to touch this status body { AnimatedImage(url: URL(string:url), options: [.progressiveLoad], isAnimating: $isAnimating) }
