Adds an easy bitrunning domain themed around sacrifing people, also makes digitital beings not care about death (#93546)

## About The Pull Request

1. Adds `Heretical Hunt`, an easy difficulty domain that tasks you with
killing and sacrificing simulated crew members. The domain has a few
ways to conquer it, as you don't need to kill all the simulated crew
members and there's some hidden loot to make use of

It's an easy domain because 
- You have quite decent armor,
- The mobs are pretty unintelligent, 
- You can always fall back and heal passively on the rust tiles
- There are many ways to tackle it

Though it's not a complete pushover, the mobs can still overwhelm you if
you're not careful.

2. Virtual beings are given a minor positive moodlet for killing people
instead of a negative one

## Why It's Good For The Game

1. I thought it'd be kinda fun if we had antag-themed domains which
soft-explains the gameplay loops or mechanics of certain antags, in this
case, heretics sacrificing people

2. You don't feel remorse for killing people in video games, right anon?
