Allows using wallpaper files without extensions

[Vlad1-1]

This resolves #52, though it introduces a dependency on the file executable. That shouldn't be a problem though, as on Arch file is required by the base package.

Ew. Why not use something like
https://github.com/hyprwm/Hyprland/blob/d6241a3086c4abfd21e91e23c83c97c3f80123d4/src/helpers/MiscFunctions.cpp#L389-L401

[Vlad1-1]

Yeah, that would be way cleaner, although the function wouldn't be used anywhere else in hyprpaper.
I will try to do something like that

at the moment, in the future, who knows.

[Vlad1-1]

I didn't completely copy the code from hyprland at all

[Vlad1-1]

That if was meant to check if for some reason the file binary, the program that actually checks the file type doesn't exist, but I forgot execAndGet logs that already

[vaxerski]

lgtm, thanks!

Just a note, as the initial comment is kind of hidden now, you might want to add file (the binary) to the dependency list on AUR when you merge this
