This PR fixes #48 and #70 by adding a callback to be called when a sticky header is pinned or unpinned, etc. It also works with reversed scrollable widgets.

Added SliverStickyHeaderActivity class that represents an event such as "onPinned"
Added the event dispatching logic to RenderSliverStickyHeader
Added callback parameters to the constructors of SliverStickyHeader
Added a new example to example/lib/main.dart

I hope you find it useful 😀
