Adds Sleep Music to Surgery/Cryo/Sleeper

Plays quiet music when you have;
- An anesthetic mask on your face.
- Been put into a cryopod
- Been put into a sleeper

TBD: Maybe make sleeping do it, but iirc even dying does sleep.

There is a pref toggle for these under Preferences: "Sleeping Music"

Example [here](https://streamable.com/pls63y) of surgery being done. Volume is higher than normal, was adjusted down to 40%.
