add new latin/german tsv with footnotes

- Update TSV format to 8 columns: BookName, BookAbbr, BookNum, Chapter, Verse, Latin, German, FootnoteText
- Add printverse_bilingual() function for side-by-side Latin/German display
- Add language filter flags -g (German only) and -L (Latin only)
- Add to_superscript_num() function to convert footnote numbers to Unicode superscripts
- Update processline() to detect and route bilingual verses, German-only, Latin-only, introductions, and footnotes
- Footnotes now display with superscript numbers (¹²³⁴⁵⁶⁷⁸⁹⁰)
- Default mode shows Latin and German in two columns with | separator
- Introductions and footnotes display full-width

New flags:
  -g  show only German (no Latin)
  -L  show only Latin (no German)
