Add language information to the TSV output (fixes #1861) #4168

Also make the font_info flag work on TSV output.

font_info has no reliable information (see e.g. https://github.com/tesseract-ocr/tesseract/issues?q=is%3Aissue+Font+Attribute+) so I doubt if it is a good idea to promote it in output |

Alright, do you want me to remove it from this PR? |

to
char *GetTSVText(int page_number, bool lang_info);

I have pushed the overload approach, it does not break the API now.

The existing code was reading
hocr_font_infobut not using it when producing output. This PR fixes that, too but it feels a rather undocumented feature without reading the source code. I wonder where to document that. Maybe as a comment on thetsvexample config?
