Cubic Leaves 1.9 (resource pack compatible)

Added support for all of the Team Abnormals Mods!

Changelog:

Updated pack.mcmeta for 1.21.6 support
Finally replaced the old lazy pack.png icon to a high quality render! (I updated the website icon as well! Also in the future I'll be able to update the icon for seasonal events :3)
Slightly renamed the file names to be more verbose/consistent:
For example, the performance edition went from "Cubic Leaves (fast)" to "Cubic Leaves (performance)".
The resource pack compatible edition went from "Cubic Leaves (compat)" to "Cubic Leaves (resource pack compatible)".
