Larion World Generation

A whole bunch of changes for a different feeling terrain. Everything is scaled up to be larger than before and closer to the goal of a fantasy-like landscape.

• Erosion is no longer coupled to continents, instead made up of a "mountain chains" function and a "swamps" function
  • This means mountains can appear at the coast and form long chain-like lines (but also sometimes giant mountainous blobs)
  • Swamps and windswept terrain can appear inland now as large semi-rare areas
• Many, many tweaks to how continents and islands are laid out
  • Larger continents with more interesting shapes
• Big changes to ridge noise - now consists of separate density functions for rivers, hills and "weirdness"
• Changes to temperature and vegetation noises
• Larion no longer overwrites minecraft:overworld/offset, instead introduces changes in minecraft:overworld/depth
  • Changes include an extra depth factor based on continents (terrain is "raised" inland except for at rivers, meaning far inland mountains are higher than coastal mountains and so on)
• Adjusted "jaggedness" noise scale to make mountains less.. jagged and shaped more like real mountains
• Adjusted river tunnelling for larger tunnels and lots of saddle river valleys
  • Most rivers are exposed to the surface now, at least partially, but tunnels can still generate under very tall terrain
