ChunkGenerator.ChunkData -> More options

Is your feature request related to a problem?

Not a problem per se, just looking for more options.

Describe the solution you'd like.

I would like to see the addition of more data passed into ChunkData, such as BiomeParams.

I've recently been fiddling with custom world generation some more.
I noticed during the noise/surface generation stages there was no access to BiomeParamaterPoints.
Doing a small dig, I realized this data could be passed into ChunkData from RandomState.sampler() (within NMS/Craft CustomChunkGenerator)

I think this information could be handy when deciding on how one would want to generate their terrain.
For example, lets say I want Minecraft to handle biomes, but I want to build the terrain.
I could use the continentalness from the biome param points to help determine with some noise whether I want terrain to be ocean/land.

Describe alternatives you've considered.

Currently just using a lot of my own noise generation (via FastNoiseLite)

Other

I'd be willing to do a PR for this, but only if this is a feature that's wanted/approved.

Start at RandomState.sampler() within NMS/Craft CustomChunkGenerator and trace how data reaches ChunkData during noise and surface generation. Determine how BiomeParameterPoints such as continentalness could be exposed for custom terrain generation; done means the additional data is available to ChunkData for those stages.
