Biome blending for tints #197

A pre-requist for this would be to get the block accurate biome in mineflayer. Since 1.15 the server only send biomes values for squares of 4x4 blocks, the client has to interpolate to get the individual block biomes. prismarine-rng implement the VoronoiLayer code that does this interpolation https://github.com/PrismarineJS/prismarine-rng/blob/master/lib/biomes/layers.js#L561 but it needs to be integrated into mineflayer (and it should be computed on demand as it is not a trivial computation and biomes are rarely needed).

Once each block has a correct biome value, blending two tints is very straightforward, we just have to put a different tint on each vertex of the cube instead of the same on every vertices.

I think we’ll still have to compute the blend a bit before putting the different colours on the vertices because the blending radius is usually larger than one block, right?

Yes this part of the computation of the tint we put on each vertex.
