[MIRROR] Adds anosmia quirk (#1890)

* Adds anosmia quirk (#82206)

## About The Pull Request

Adds anosmia quirk. Anosmia, also known as smell blindness, is the loss
of the ability to detect one or more smells.

I tried to find all smells action and (most likely) update all of them,
unfortunately I can't change descriptions for this quirk.

## Why It's Good For The Game

Some characters will be able to not feel smells
That affect:
* Gases feelings and alerts (CO2, Plasma, miasm) - you don't feel them
* Bakery and cooking
* Changeling ability to feel other changelings by smell
* Some unimportant spans

* Adds anosmia quirk
