Let Cartographers sell maps to every possible biome

It is extremely common for players to use tools such as chunkbase, simply because they do not want to explore. That's perfectly fine, it's natural for some players to enjoy exploring less than others. However, I'd imagine they would be less inclined to use external tools if there was an in-game alternative. I use chunkbase myself to find biomes as I don't want to spend my time searching forever for a jungle. I would likely consider it cheating, were there no alternative. Cartographers can fix that. Let cartographers have the ability to sell maps to any existing biome, the way librarians do with enchanted books now.
