Primal Winter 1.15.2-1.1.0

Entities now spawn!

• Fixed issues that were causing vanilla surface passive mobs not to spawn in winter-ificated biomes during world generation.
• With this, polar bears now spawn commonly in the snow, and on top of the ice covered ocean biomes.
• Large goups of snow golems now also spawn occasionally.

And some technical changes:

• Added some tags which can be used to configure animal spawn conditions.
• All winter-ificated biomes have the COLD and SNOWY biome dictionary tags applied for any mod that uses those.
• Trimmed down some image sizes courtesy of Darkhax.
