Changes:

• Updated pack format to 79 for Minecraft 1.21.6
• Improved the efficacy of forcing efficient food items to become unstackable. It is now more punishing of attempts to circumvent the system, including trading with Villagers
• Made all Villagers wear unbreakable Leather Boots that are not dropped when they are killed. This should allow Villages to survive better despite being surrounded by Powdered Snow
• Changed the Indestructible advancement icon
