Major update (Likely final unless something breaks)

- Now works on medics with Miracle Worker
- Now can be deconstructed back into bandages
- Custom Affliction (Doesn't rely on Miracle Worker now)
- Custom Icons
- Custom Sprite

Revamped how the status effect is applied. Fixed an issue where characters could still die if they were left out for too long / or too many times in one round.

Immortality buff now applies at 0 vitality instead of -50 vitality. Aimed to reduce the chance of characters being one-shot before it activates.
