Alternate biome transitions

This datapack adds transitions between biomes (small blobs of each extend into the other) to break up the harsh transitions between some biomes. See the gallery for images of what this looks like. This datapack also makes colder biomes generate further out higher up to make mountain transition more realistic.

### Finding biomes

Because this datapack makes colder biomes generate higher up, the `/locate` command may find biomes up in the sky (i.e a plains 400 blocks above a savanna). This is especially common when increasing the height of a world. To counteract this, you should try to find the biome in an unmodified world. The same biome should be there in the world with this datapack (though sometimes there could be a closer one, if one almost generated, this datapack may generate a transition to it).

### Customising

As of version 1. 1. 2, internally there is a config. Due to datapack limitations, you must edit the datapack to do this. To do this you should

1. Unpack the zip file (copy contents into a new folder). For readability, I will refer to this folder as `datapack`. 2. From the folder `datapack`, go to `data/alternate_biome_transitions/worldgen/density_function/constants/`. 3. Edit the constants, currently - `temperature_height_drop_amplitude.json` controls how much the biome temperature drops when travelling upwards. 0 means no drop, 1 means default drop, numbers between them will blend between the two. 4. Save the files. 5. Create a new zip file and copy the contents of the folder `datapack` into it. This is now your modified version of this datapack.
