Larion World Generation 4.3.0

Simpler continent shapes. Larger in general with narrower oceans inbetween.
Low erosion (mountains, highlands) is more common, high erosion areas (swamps,windswept) have simpler shapes.
Smaller humidity zones. Made "Extreme" humidity (dark forest, sunflower plains etc) less common, leaving more space for the rarer in-between biomes such as birch forest.
Terrain shape tweaks - more jagged mountains, less super-steep cliffs, more hills in eroded areas.
Made river tunnels more common and able to go under mountain peaks again.
The ugly chunk border line artifacts are now less common.
