This fixes a slight deviation from vanilla in that we incorrectly use the x/y/z coordinates rather than passing section coords. This is because the old method (getBiome) uses block coords, while uncached noise uses the section positions.

This whole "optimization" creates a big enough deviation in that it probably isn't noticeable. So maybe in future, this should be made configurable?
Note: This is an old issue, not hardfork issue.
