Adding a new Armour trim and trade armour trim with villager

Hi, I'll explain why there needs to be a new armor trim. First, to add to the mix of some of the old trims. Second, For structures that don't have special armor trim such as sulfur mineshafts, dungeons, and abandoned camps (for abandoned camps, I don't know what the loot is yet) And finally, the reason why trim should be able to be sold by villagers is so that we or players can get trim more easily without having to go to the structure. Maybe that's all, thank you. (I hope to get cherryblossom cape and office mojang💔, oh sorry, just kidding)
