Support for SwiftUI State and Data Flow in ASDisplayNode

[mycroftcanner]

It would be really nice if we could support the following property wrappers in a Node:

@Binding to create a two-way connection between a view and its underlying model.

@EnvironmentObject a dynamic view property that uses a bindable object supplied by an ancestor view to invalidate the current view whenever the bindable object changes.

@State through which a view reads and monitors the value.

It shouldn't be hard, I'm gonna look into it.

Any news on this one?
