Description

This is actually a 4-year old feature request, formulated in my comment to issue 918 (https://groups.google.com/forum/#!searchin/tesseract-issues/issue$20918/tesseract-issues/U7g6ntPXYds/aAyTuIFBUhwJ) but I really need it now, cf. https://groups.google.com/forum/#!topic/tesseract-dev/d4QQdaq3LF0.

Research direction
Examine the TSV output implementation in Tesseract, likely in the source files under `src/api/` or `src/ccmain/`. Determine where the language detected is stored and how to append it to the TSV output lines. Review the referenced forum discussions for additional context on the desired behavior. Propose a change that adds a new column for language code in the TSV output.
