FinancialGooseandGitHub e98cb75c57 Refactor gasmix mole change into a proc (#95327)
## About The Pull Request
Refactor the majority of the current gasmix mole change use cases into a
proc called adjust_gas which simply adds the designated mole count of
the species into the gas mix while also handling asserting the gas and
garbage_collect()
I also added adjust_multiple_gases and convert_gas() for modifying
multiple gases and within a gasmix

## Why It's Good For The Game
Lemon wanted this to be done as part of the air group refactor 

## Changelog

🆑
refactor: refactored majority of gas_mix mole change into adjust_gas()
