Fireflies Sprites

I have a few item texture tweaks I figured would go poorly in my GUI pack but wanted to share with the world.

• Changes all book item shading
• Tweaks melon and glistering melon shading
• Tweaks totem of undying colors to make the eyes clearer and the gold brighter

Compatible with all versions since 1.20.2! (and technically works since 1.13ish but will probably yell at you about version incompatibility)

Feel free to steal any of these textures, I don’t care!
