Leveling up villagers

Umm hmm… where’d my XP go. Maybe the cleric or librarian has it. Villagers and wandering traders can now pickup xp to raise their trade level so xp bottles would be pretty handy. Speaking of xp bottles and villagers interact with a nitwit using a emerald and an xp bottle in the off hand to give him custom trades. Nitwits can be recruited using a golden apple. Use dye to change the color of their robes. Give them hoods similar to the wandering traders by interacting using carpets and remove hoods with shears
