Reference ls_extended project

Hi @yellow-footed-honeyguide , I actually saw the same kind of app in CachyOS, it's the default there for "ls": https://github.com/Electrux/ls_extended Coincidentally, it's also a pure C project. Please note: I'm sharing this for the outlook only, not to misrepresent your effort. Maybe you wish to mention it in the References section.
