Store per-region biome list in IndexSet 
Index into the biome list instead of duplicating the biome data for each
coordinate. This reduces the size of the processed data and speeds up
encoding/decoding.

world/layer: avoid iproduct-based iterator in inner loop 
iproduct iterators are fairly slow. As the iterator implementation is
now unused, it is removed as well.

Split up BlockInfo type 
By storing block types and depth values separately, the processed world
data can be compressed better, decreasing data size by ~10%.
