New trades

Trading with witches: only possible if player wears a pumpkin head. Would not be interested in emeralds, instead interested in spider eyes, nether warts, etc., and since witches aren’t meant to stay for long, it should be similar to a wandering trader’s system, offering tadpole buckets to make it easier to obtain frog lights, slime balls & honey for those who need it for redstone, brown mushrooms, costume heads of other mobs (spider head, fox head, iron golem head, etc) and potions that the player cannot brew, such as shrink potions, blindness potions, and levitation potions, all randomized. Upgraded fletcher: the fletcher villager has potential to trade specific variants of fireworks, which opens up the opportunity to revamp the fletching table itself and add a new item to it: firework recipes for new sounds and patterns, found in new loot from chests across the world or from fletcher trades. Fletcher could also sell a firework with a lingering potion effect.
