Fix on Wandering Villagers

Currently the wandering villagers almost no player trades with him because he trades things that are not very useful and very expensive in the game, these villagers are seen everywhere: and yet every player ignores him.

The wandering villager also has another problem and that is that they break the purpose of exploring biomes because they can even give you a cherry blossom without even reaching the biome. In addition to making it very easy to get emeralds in this latest 22w31a instant version, by trading to get an emerald to the player in exchange for a bottle of water, this unbalances the difficulty of the game.

It is for all this that I propose that they change and redo the trades of this creature, first always putting in the different trades of each wandering villager that they have limits to achieve them, this because the wandering villagers are wandering and that is why it is not correct that they be can lock up to trade forever, so the player will have to find another.

Second and most important, give them new and useful trades both for players starting a game and for those already advanced, these trades must be balanced that encourage exploration (not take away its purpose), such as maps to nearby villages and basic tools that can be get in exchange for copper bars, not emeralds. While they can also exchange unique items that you only get from them for emeralds, such as a unique blacksmithing mold or an item for villagers to follow the player.
