Add biome color computation
Rather than using fixed values for all biomes, generate grass and foliage colors based on (height-dependent) temperature and rainfall parameters. This changes a lot of colors; in general, the new colors should be closer to the actual Minecraft rendering. It also fixes a few colors that were completely off (like in the badlands biomes) and adds the MC 1.13 biomes (which were rendered in black). Some of the newer biomes (warm/cold/... oceans) don't have proper parameters yet, and we do not derive the water color from the biome yet. Fixes #1.
