fixes:
- treasure enchants being selectable within the enchantment table menu
- frost walker resemblance to decompiled legacy console edition
- enchantment table featuring hot-swappable abilities where the player could replace one tool with another whilst keeping the exact same potential enchantments in the enchant menu
