Compare file contents with old data before writing 
Do not writeoutput files when their content hasn't changed. This saves
time for incremental generation (as compressing a PNG takes much longer
than decompressing it) and avoids modification timestamp updates that
might trigger subsequent generation steps.

Add smooth transitions between biomes 
Simliar to the way biome transitions are rendered in Minecraft itself,
add smoothing by averaging biome-based colors over all biome values with
distance ≤3 (1-norm).

Collect biome data 
We store the biome data as grayscale images, as biome indices are
represented as bytes and we get PNG compression for free.

Add quirk for stone_slab rename 
The old stone_slab block from pre-1.14 has been renamed to
smooth_stone_slab, and the name stone_slab was reused for a new block.
Resolve the palette entry depending on the chunk's dataVersion.

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.
