[Feature] Image pipeline mutator

Works similarly to the REPLACE mutator, but instead of a noise function, it would accept an image, working the same as the IMAGE biome provider.

I feel like this would be better as a source rather than a mutator.

Implemented as a source via the pipeline-image addon https://terra.polydev.org/config/documentation/image/pipeline-image-source.html
