Datatable: Add reference to virtualScroller

[michael88]

Describe the feature you would like to see added

Please provide the possibility to get from datatable a REF(erence) to the underlying virtualScroller Object/Module to call its exported methods

Is your feature request related to a problem?

I tried to position the datatable (with virtualscroller) to a specific Index.
I can see, that in the virtualscroller Module (virtualscroller.esm.js) there exists (exports) the function "scrollToIndex" .
But I can't get a reference to VirtualScroller to call this method/function.

Describe the solution you'd like

datatable should export a ref to Virtualscroller

I think all components using VirtualScroller need a way of getting the ref

After this fix is merged you will be able to do to dtRef.current.virtualScrollerRef to get access to the virtual scroller ref
