BlueMemesauce a698aa2fd5 Simple and basic mobs can breath pluoxium (#76694)
## About The Pull Request

Fixes #76661

Also adds new PLUOXIUM_PROPORTION define, this is set to 8 which is
currently how better pluoxium is at metabolism compared to oxygen
## Why It's Good For The Game

Since pluoxium is 8 times as effective as oxygen, mobs only need 0.625
mol of it compared to 5 mol of oxygen. This is a very small amount,
maybe it should just be the same as oxygen?
Also pluoxium and oxygen are counted together, so you could have a mix
of 0.5 mol of pluoxium and 1 mol of oxygen for example.
