Bluebirds Tweaks

Changelog v1.0.1

• Added Custom CIT Enchanted Books for common max enchants
• Updated heavy core model to support 1.21.4
• Removed most emissive items in favor of a creating a new pack

Note: I'm probably gonna remake the entire pack for 1.21.5 because they removed some core shader support that I used to make it compatible with multiple versions
