## About The Pull Request
In #68385 a lot of impure reagents was converted into inverse, but not
Aivime, Lentslurri, Libitoil and Eigenswap.
This PR:
1) Returns Aivime, Lentslurri, Libitoil and Eigenswap to cookable state
with inverse_chem_val
2) Makes code less outdated i think
3) Remakes Aivime (adds the ability to stack blur)
4) Change eigenswap inverse_chem_val from 0 to 0.1 (zero purity is
unreachable)
Fixes#79692
## Why It's Good For The Game
This is an effort to add unused reagents and to provide additional
options for a Chemist to experiment with
## Changelog

fix: Aivime, Lentslurri, Eigenswap and Libitoil can now be cooked again.
