What is the problem the feature request solves?

We currently unpack dictionaries before SortExec, which seems inefficient. I experimented with removing this unpacking and was able to run TPC-H without error, but TPC-DS failed with an out of bounds error.

It is possible that we will need to make changes in upstream DataFusion to support this.

Describe the potential solution
