Note: Comment by Wes McKinney (wesm): This might be most easily implemented by using Take, i.e. Take(ctx, dictionary, indices, &out), which we ought to implement soon.

Note: Comment by Uwe Korn (uwe): We can implement this soon using Take but I'm taking a shot at this currently to get the functionality in parquet-cpp and to understand the new compute library.
