Personal refactor (#1)

* refactor(props): change wrap-tag type

* Updated wrap-tag props type to accept component so a vue component
can be passed as wrapper
* Gist: vue-smooth-dnd uses Container to wrap list of items
that are draggable

* refactor(render): pass props to wrapping tag

* Pass extraProps to container tag so, custom values can be passed
to custom container

* feat(range): add method to get range

* Add method to get current range of shown items, so the dragged
item can be indexed based on the start range index and dragged index

* build: run prod build for new changes
