Fix incorrect snowy dirt model (Fixes #111)

Add block tag translations

Fix compatibility with terrablender-added biomes, requires some hacks to work on NeoForge (closes #108)

Make more hostile mobs powder snow immune and walkable

Add missing block translation, add more blocks to the list of snowy underneath replacements.

Update publishing for 1.21.1

Add snowy azalea and flowering azalea leaves. Add snowy lily pads. Update bamboo textures, increase spawn probability for strays.

Add snowy bamboo, and make replacement of blocks underneath snowy frozen plants more aggressive, as to prevent additional blocks showing through.

Fix incorrect config value, smoothen fog interpolation, use wrap instead of redirect for surface system mixin.

Cleanup for config platform handling

Remove registry sync mixin, as the fix has been implemented by both respective loaders.

Update to 1.21.1, and port config to use loader-specific implementation. Fabric keeps using epsilon, Forge uses native which is satisfiable now due to fixes in nightconfig, and a builtin config UI.

Add snowy red/brown mushroom blocks and mushroom stem

Refactor config loading to occur earlier, don't leak server, refactor more biome/raining/coldEnoughToSnow() checks out in favor of dimension-specific config.

Fix /weather thunder being ran on opening existing worlds
