Not sure if I understand correctly, but the old version (legacy files with pale colors) has sprite sheets in a folder called "Sprite Sheets" (top level). But you want the new version (darker, more saturated) as sprite sheets, correct? If so, I would sadly have to refer you to sprite sheet creating programs (or texture atlas generators). Or did I misunderstand something? :-)
(There are also no legacy files (pale color palette) in the isle-of-lore-2-hex-tiles-regular-final.zip)
