Adventuring Villager/Trader

Like A Wandering Villager/Trader, but they sell maps or services to guide players to new biomes and/or key structures (Desert temples, other villages, trial chambers, dungeons etc).

Like A Wandering Villager/Trader, they can be found with mountable mobs (Horses, Llamas, etc) and can sell supplies for items (Maps, cooked food, spare tools (highest maybe iron tools)).
