Added more base stuff:
- wget is generally useful
- outils and minisign for signing stuff
- xxd for binary stuff
- ugrep as a potential ripgrep replacement
- fswatch for doing stuff with inotify
- moreutils to be fancy
For the rest:
- remove spotify stuff from media, add other useful programs
- replace youtube-dl with yt-dlp
- add stuff do dev
- add further_dev for less common stuff
- make Gemini stuff more generic
- add comic book browsing to zathura
Also make youtube-viewer use yt-dlp.
