New villager profession "Trainer"

This resident will usually spawn in pens with animals and he has the ability to feed animals. His working block is "Feeder". This block allows the player to put, for example, Wheat in it and when a mob that feeds on this food approaches him, he can eat the food himself. That is, a chest that feeds animals. Also, the resident, like the "Farmer", has its own peculiarity. When his inventory is replenished with, for example, wheat, he does not make bread, but feeds the animals with wheat. This unique resident will allow you to make a mob farm, a wheat farm without a full inventory of grain. This is a very good mechanic that will allow all players to automate the reproduction of their animals. You can make restrictions so that the resident can only feed farm animals, that is: pigs, sheep, cows and chickens.
