Wandering Trader Map Sale

When a wandering trader spawns, it picks a location around 500-1000 blocks away from its location prioritizing unexplored regions that aren't an ocean (Unless the ocean is a coral reef). It then draws an imaginary line from that point to where it spawns and sells items from biomes one would encounter if they traveled along the line. A player could also buy the map with the line on it with emeralds if they want a better way to find the new area. This should be added to improve the use of the wandering trader because, in its current state, players don't give it as much use.
