This feature is not related to a problem in Sodium.

Describe the solution you'd like
I would like Sodium to expose WorldSlice.getBiome through some sort of interface or API.

Describe alternatives you've considered
One alternative I know of is mixing into Sodium, but this can be unstable so it would be better if this functionality was built-in.
While writing this I realized I do not need to mixin as I can just cast to WorldSlice directly, but once again this could be unstable.

Additional context
This feature is for a mod that requires getting the Biome inside of FabricBakedModel.emitBlockQuads, but BlockRenderView doesn't expose a BlockPos or int coordinates to Biome method or function. I was able to mixin to vanilla's ChunkRendererRegion to allow this functionality in vanilla, but it will not work with Sodium because it does not use the ChunkRendererRegion.
Additionally, accessing the biome using MinecraftClient.getInstance().world.getBiome(BlockPos) might not work with mods such as Immersive Portals. I am not sure about this though, so please correct me if I'm wrong.
