Prismarine Shader

------- Prismarine V3.1a -------
1) Added perbiome fog and sky! They have unique colors in every different biome. Not compatible with iris
2) Removed planar clouds, now you only have volumetric ones. They are disabled by default
3) Fixed nebula fog being rendered incorrectly and not fitting the shape of the nebula itself
4) Modified some colors and stuff
5) Increased default volumetric fog thickness
6) Fixed light flickering, now it works again
7) Added albedo tinting to the emissive blocks. Increases the detail of original texture and prevents it from being tinted by the blocklight color
