Added custom responding page event

[devyhan]

Added a way to customize willTransitionTo and didFinishAnimationg delegate method.
Please check it out and accept the request if you like it. 😆

example

iPages {
    Text("iPages 🤑")
    Color.pink
}
.didFinishAnimationg { _, _, _, _ in
    print("Insert didFinishAnimating action code here")
}
.willTransitionTo { (pageViewController, viewControllers) in
    print("Insert willTransitionTo action code here")
}

It is implemented so that it is not expressed in "page view initializes" for readability when writing code.😀

To get rid of long closure expression in function argument you can use typealias.
