Shoutout to peA_sh0ter for tracking down some issues!

• Incorporated the new Java Edition 1.21.9 "Copper Age" features
• Haphazardly modified Bookshelf Block Module for 1.21.9
• Changed pack.png
• New copper equipment uses the new copper IDs
• Existing copper equipment has been renamed "old copper"; the old armor set retains its original textures; old copper nuggets still work to craft copper scrap
• Tweaked copper tools to use new textures
• Tweaked dyed horse armor overlay textures, and added overlay for the new copper horse armor
• Added a custom copper chest recipe (cheaper than vanilla)
• Changed chest recipe to use flint for the chest frame
• Copper chains and bars are climbable like their iron counterparts
• Chains are significantly cheaper, requiring only 4 nuggets each
• Copper lanterns behave like a hybrid of iron lanterns and soul lanterns, damaging specters and producing green flames; copper lanterns render 3D like the others
• Added bandage and honey-sulfur poultice items for healing
• Tweaked torches to render vanilla 2D models in GUI (3D models are still used in other contexts); the new copper torches received the same treatment
• Fixed issue with lit torches having blue text instead of white
• Tweaked enchanted book duplication templates to have a max stack size of 64
• Boosted campfire healing range to a 14 block radius
• Campfires can no longer heal players when there is a monster within a 12 block radius
• Campfires now check whether they are within a non-underground dimension before trying to heal a player
• Added hints regarding standard campfire ventilation and soul campfires
• Added translation string for "failed to locate campfire"
• The sandstone layer now has rare skeleton, zombie, and creeper spawns
• Cave-in functions check for support blocks earlier
• Cave-ins form spheres of falling blocks centered on the first block to fall
• Cave-ins can cause unsupported floors to collapse
• Falling blocks spawned by a cave-in can directly hurt entities
• Landing on an unstable block after a 5m+ fall will cause that block to fall
• Fixed broken area effect clouds for poison cloud, radiance, and totem of regeneration
• Deleted some unused files
• Deleted broken line from soul campfire activation function
