This PR aims to add merge tool to merges multiple ORC files to produce a single ORC file.
Why are the changes needed?
In the ORC 1.3.0 version, the OrcFile#mergeFiles method was introduced by ORC-132 , which supports merging multiple ORC files into one ORC file.
However, when merging, we need to write Java code to call it.
There is no simple command that can be called directly.
