Description

If any child of the Screen operator adds a selection vector to its record batch. The screen operator ignores the selection vector and outputs all the data (even the ones not present in the selection vector). It should do one of the following
1. Throw an exception indicating it does not handle selection vector 2
2. Handle the selection vector. Project handles the selection vector, we could possibly leverage some of the logic.
