Support isDraggable, dragBeginHandler, dragChangeHandler, dragEndHandler for PointAnnotation in SwiftUI

[Yourney]

New Feature

Currently I see that I can set isDraggable in the PointAnnotation is in the initialiser:

/// Create a point annotation with a coordinate and an optional identifier
/// - Parameters:
///   - id: Optional identifier for this annotation
///   - coordinate: Coordinate where this annotation should be rendered
///   - isDraggable: Determines whether annotation can be manually moved around map
///   - isSelected: Passes the annotation's selection state
public init(id: String = UUID().uuidString, coordinate: CLLocationCoordinate2D, isSelected: Bool = false, isDraggable: Bool = false) {
     let point = Point(coordinate)
     self.init(id: id, point: point, isSelected: isSelected, isDraggable: isDraggable)
}

... but it does not seem to do anything in SwiftUI.
In the PointAnnotation.swift file it is even mentioned that this is not supported in SwiftUI:
/// - Note: In SwiftUI, draggable annotations are not supported.

Why

I would like to allow the people who use my SwiftUI app to drag PointAnnotations on the Map.
