Adds a new brand of cigarettes, Mainthol Greys (#91328)

**We all like a little flavor, and a new brand in the sector promises a
dark smoke, questionable trace compounds, and the robust flavors of
maintenance...**

## About The Pull Request
I've added a new brand of cigarettes! Mainthol greys, now available in
hacked cigarette vending machines for an immodest sum, hand rolled &
grown in the Sybil sector. The syndicate stock some stolen surplus too.
The goal was to create another nice little flavor item, a compliment to
grey bull and other maintenance loot.

<details>
<summary>Chemical contents in code, for the joy of discovery!</summary>

  ```
1u oculine is in every cigarette, an imperceptible buffer against the
welder harming an enterprising assistant's eyes.
Extremely trace amount for cigarette microdosing.
Each cigarette has a 40% chance to have an extra reagent from a list of
14 minor toxins, drugs, and things like glitter.
They're inconsequential via cigarette, but still noticed and
experienced.
  ```
</details>
I tested these bad boys extensively, blending them, ate them, blinded
myself with a welder, spammed a health analyzer while smoking to gauge
chemicals and ensure intended effects are noticed and add a nice je ne
sais quois.

**Our sprites!**

up your assisting.
