bin: Rewrite Clapper player binary
A rewritten Clapper video player made using "Clapper" and "ClapperGtk" libraries. Since both libraries from this repo are in C, newly rewritten Clapper binary is also in C to avoid mixing different programming languages in a single repo, thus making maintenance easier. Not depending on GJS gives us also an additional benefit of supporting different operating systems or linux shells without pulling GJS as dependency. Licensed under GPL-3.0-or-later.
