Remove unused code in LodNodeBuilder

I don't think using a 3rd party generator is a good idea; even if it is much faster than vanilla MC.
For a couple of reasons:
1. we could run into issues where the 3rd party isn't updated fast enough
2. the 3rd party generator may not generate the same terrain/biomes/etc.
3.  we wouldn't be able to generate mod terrain
