[PRQ#57951] Deletion Request for didjvu

MarsSeed [1] filed a deletion request for didjvu [2]: Djvu is practically dead except for readers and tools than convert from it to other formats. This Python2 based tool is EOL since 2019 and is not buildable from AUR. But it is also useless to keep. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/didjvu/
