Maintenance status; community fork

It seems that Meta is not interested in this research project any more and it is not maintained, e.g., bugs like #232 that renders the project unusable are not fixed.

If so, we need to fork this project and maintain it as a community. This is the best PDF-to-Markdown converter I know of; it is much easier to maintain a community fork than to write a new one from scratch.

Thoughts please, @breisfeld, @YuCheng-Qi, @williamparson, @YodaGitMaster, @Halle-Astra, @she3o, @MaksimMrvica-plus, @hongyi-zhao, @sparsh35, @ivanmladek, @S1M0N38, @itsaphel, @bryanyzhu, @luckymore, @fqassemi, @robertobagnato, @Vidminas? (Randomly pinging some people who seem to have been active.)
