Subject: [PATCH] kakoune: add colorSchemePackage option

This makes it easy to declaratively manage the color scheme for kakoune via a nix package in your ``~/.config/kak/colors`` folder.
The color scheme can then be declaratively selected by name using the existing hm option ``programs.kakoune.config.colorScheme``
