[Feature Request] provide way to expose quills undo redo stacks.

[krishnaprasadgandrath-nooor]

I want to access quill controller's history changes so that i can integrate quill's undo redo operations with whole app's undo redo operations.

any news on this one?

Seems like if I want to store the history as well, it would be enough to store the lists of undo / redo from the History object ?

controller.document.history.stack.undo
controller.document.history.stack.redo

And as we can set the values in HistoryStack, when we load from database, we can just set them after creating the controller from the deltaJSON. means we would store:

controller.document.toDelta().toJson()
controller.document.history.stack.undo
controller.document.history.stack.redo

the History#_change method does not seem to conflict with this idea. Any other limitations? @EchoEllet
