Generate missing Catppuccin palettes from a base file (e.g. generate a dawn.conf & a dusk.conf from a storm.conf file)

Usages:
#0: $(basename "$0") <flag> [arg]

Flags:
	-f, --file			specify file (mandatory)
	-v, --verbose			increase verbosity by 1
	-o, --original-palette		the palette used in the based file (given by --file)
	-l, --lowercase			replaces with lowercased hex codes
	-c, --coerce			force the creation of new palette files (useful when those files already exist)
	-p, --prefix			specify which prefix to use for the hex codes. Surround it with double quotes if needed.
	-h, --help			see this message
