Nightosphere

It does a variety of changes to the nether, biome distribution remains the same.

Changes:

Higher nether generation up to 224

The top 32 layers are netherrack with small caves, so is more like 192, and is not everywhere but when it happens it will be more open

Why this?

256 height takes away from the lava ocean which is a key part
of the nether level design but I do want the nether taller

The carvers don't go down bellow the lava ocean

Why this?

Simply because an impossible to cross lava barrier is neither
fun or adds depth, is just a stop sign

Higher amount of quartz

Why this?

The demand for quartz can be high for building and quartz is a
common source of experience for players

Ancient debris generates more scattered

Spawns mostly in single blocks but is more common to stumble to

Why this?

Reduces the chances of rng playing with you, by having higher
odds of hitting netherite even if smaller amounts it makes the
progress towards getting the netherite be less aimless

New cave rivers at the lava sea level

Why this?

It helps when traveling with a strider

Crimson and warped giant fungi now checks the terrain in order to place

This is mostly a technical thing

Why this?

It stops them from generating in the small crevices where they looked buggy and got cut so much

Unhardcoded the basalt delta columns

This is mostly a technical thing, but I just recreated the columns in a way which isn't as harcoded as vanilla does it

Why this?

It is more structure friendly.
