Fireflies Sprites

Tweaks to various item textures:

• Melon and glistering melon shading adjusted
• Book, written book, book and quill, and enchanted book all got shading tweaks
• Totem of undying a little closer to the color of minecraft gold and with more noticeable eyes

Will technically work on versions back to 1.13 but will yell at you that it's incompatible.
