* Rename `cups-kyodialog3` -> `cups-kyodialog`
* Update from 8.1601 (2016) to 9.2 (2022) with support for more and
recent printer models (170 vs. 373 PPD files)
* Make Qt GUI optional to reduce closure size, Qt4 -> Qt5
* Avoid full paths to kyodialog filters in PPD files. A PPD file is
copied to /etc/cups/ppd/ for each configured printer and is not
updated when the cups-kyodialog package is updated, thus,
potentially creating dangling references to /nix/store or invoking
the old version of the cups filters.
