> This is a follow-up task of ORC-1012. Currently we have options for the tools 
> to work on specified top-level column fields. However, ACID ORC files usually 
> have nested structure. We need the type ids to specify nested columns. As an 
> extension, adding support for column names will also be helpful. So we don't 
> need to manually convert column names to type ids.
