Is your feature request related to a problem or challenge? Please describe what you are trying to do.

I am trying to use RowSelection / RowSelection::intersection from arrow #3003 in datafusion but it turns out there is no way to either get this information rom RowSelection nor any way to access to the underlying RowSelectors

Describe the solution you'd like
A way to get an iterator() that iterates over RowSelections

Describe alternatives you've considered
