Adds Hereditary Manifold Sickness, a Chronic Illness Quirk (#75035)

## About The Pull Request

Adds a new quirk called Chronic Illness. It provides a -12 score as it's
a pretty life-altering quirk, but could give way to interesting RP.

- Hereditary Manifold Sickness (HMS) can not be cured, it can only be
delayed and treated using a new unmakable vaccine called
"Sansufentanyl". You spawn with 6 pills and are able to order crates
containing 12 more from cargo as it's proprietary to Interdyne.

- HMS has 5 stages total.
Stage 1 does nothing
Stage 2 gives minor effects 
Stage 3 becomes debilitating
Stage 4 is a danger zone.

Upon reaching Stage 5, there are 4 possibilities, 1 is a recovery back
to stage 1, and the other 3 are deaths which I won't explain here to
avoid ruining it. (read the code I guess.)

This also adds a new traitor objective to infect someone with HMS.

- [x] Correcting the chronic aspect.

- [x] Add traitor objective.

- [x] Tweaking for fairness.

## Why It's Good For The Game

HMS is a new quirk that gives a much more hardcore junky or tumor
playstyle. Neglecting HMS can mean the end of your shift. it's not
something you want to mess with.

It puts a reliance on cargo rather than medical for a quirk and gives a
use case for money. (price may be tweaked still). I think it'd be
interesting to see if people will start mugging or robbing the vault
more to get their life-saving medication.

## Changelog
🆑
add: Interdyne has released a new medication to treat those who are in
the wrong timeline!
add: Interdyne has also realized this is VERY profitable! They've begun
arming their operatives with an autoinjector.
