WillPopScopeLoader class

Use this class instead of WillPopScope to control the ProgressLoader when the user tries dismiss the enclosing ModalRoute.

This can be tuned to prevent the user from popping the route, or to have the ProgressLoader dismiss itself when the user pops the route.

Note that, like Flutter's WillPopScope, this does not prevent navigation from code using Navigator.pop.

IMPORTANT: WillPopScope is a bit broken in Flutter on iOS, and will prevent users from navigating back even if onWillPop returns true. This widget relies on WillPopScope and suffers from the same issue. See here for more: https://github.com/flutter/flutter/issues/14203
