Ambient particles for Deep Dark

I think having occasional particles, alike those in the most recent nether biomes and in the Lush Caves, in the Deep Dark would be a very useful insight for the player to have a general sense of where the deep dark is, especially when mining outside of caves. I think this is important since the Deep Dark is a vertical biome which is not apparent from surface level and indistinguishable on a map. Something alike a sculk-blue spore would be an improvement to the biome's ambience as well as a valuable insight to a player who might otherwise unwittingly come too close to a mass of sculk, without relying on the debug menu to inform the player of their current biome.
