Armorful

This release updates the mod to 1.20.6 and migrates the project to the stonecutter build system, allowing me to develop updates across many game versions at the same time!

• Added armor for Vexes
• Added armor for Witches
• Fixed rendering issue with Pillagers where the helmet would not be correctly offset.
• Fixed rare issue where sometimes Pillagers never spawned with crossbows if they also spawned with Armor.
• Fixed issue where wave loot tables were offset by one due to a datapack update in 1.20.1
• Fixed placed feature crashes (caused by C2ME conflict)
