More refinement on soil

[blulightspecial]

I actually mention what I think in the document.

• Try combining the rock outcrop and rock ledge into one
• Try combining rubbly, bouldery, very stoney, extremely stoney etc together.
• Try removing low occurrence features from the new soils.

• I also think there's definitely something to the way Yang combined 35, 38,39,40.
  • I'm going to have to look at my translated versions of those features and see what they have in common, probably, there's probably like 1 or 2 features that they have in common that we might want to give additional weight to.

Removing low occurrence features had mixed results. Made some models better, others worse.
