New space ambient track (#76547)

## About The Pull Request

Adds a new space ambient track made by me to the game, supposed to be a
bit scarier than the others that were recently added as I feel that
they're a bit too happy (not to diss I really like them), also cleaned
up a bit of ambience.dm as the medical portion of it didn't follow the
same rules as the other ones. also also this will only be used for
tgstation so license wise I think this is CC BY-SA 3.0 but I'm not sure
so correct me if I'm wrong, also this is my first PR so yeah. Here's a
link to listen to the track https://voca.ro/18WvrGORDDdR

## Why It's Good For The Game

Variety is the spice of life.
