add draggable_scrollable_controller

[dickermoshe]

Added useDraggableScrollableController with tests

Didn't edit readme or changelog
Lmk if you want the tests changed

[davidmartos96]

I'd say this hook would benefit from the changes in #415

Current implementation of useDraggableScrollableController is not disposing the DraggableScrollableController.

@davidmartos96 Good point!
I copied this from Expandable tile controller. I forgot that that isn't disposed.
I'll fix later

[dickermoshe]

Fixed dispose issue
If @rrousselGit plans on merging #415 I'll rebase and push
