Deeper Nether Biomes

I've always been annoyed by the Soul Sand Valley and Basalt Deltas biomes added in the Nether Update 1.16. I love their concept and appearance, but there's one significant drawback.

These biomes exist only on the surface. If you dig just a little deeper, you'll immediately encounter the regular netherrack layer. It makes no sense for huge cave biomes to be so shallow. This modification fixes this issue.

Here's what this mod does:

1. During the underground generation stage for Soul Sand Valleys and Basalt Deltas, it adds the correct versions of nether quartz and nether gold to the respective biomes, replacing netherrack and their own block types.

2. At the final generation stage (top layer modification), it processes the area and replaces the maximum amount of netherrack, nether gold, and nether quartz in the respective biomes with appropriate filler blocks. This stage is chosen specifically because it's the final step in the generation process and has minimal impact on other modifications.

It's recommended to pre-generate the Nether when using this mod, as replacing all netherrack blocks may cause some delay.
