Larion World Generation

Not tested with 1.21.2/1.21.3 but might work.. please submit a GitHub issue if it doesn't

• Altered continents, nicer shapes and more variation in sizes. Also affects mushroom islands
• Tweaked erosion noise for more sudden shifts between erosion levels (=more cliff-sides) and better mountainous area shapes
• Removed the "extra offset" that affected terrain height, after some testing it turns out it negatively affected the aesthetic of the game especially in mountainous areas.
• Tweaks to ridges (peaks/valleys), made the valleys go much deeper and sometimes generate large lakes.
• Removed river caves in mountain areas, instead generates deep saddle valleys. I liked the river tunnels but they felt too unnatural.
• Altered the temperature bands to have more equal sizes and also be a bit more unpredictable.
• Altered vegetation noise to be less janky.
