Comment 12 for bug 1829562

Erich indicated to me they did not know how to structure the debian/watch file. I assisted them in that regard, using https://wiki.debian.org/debian/watch#GitHub as a 'starting source' as the 'source' they were pulling from is at https://github.com/DISTRHO/DPF-Plugins/

The source code in the debian/watch I just added to their code repository with their permission (https://git.launchpad.net/dpf-plugins/commit/?id=5b6c3f2d5c0dae3bd4887cf3b9b294f4459e3f4d) includes a working debian/watch that properly pulls from the upstream tags and source code downloads. (according to uscan anyways)
