[Port] EFN Noise filter (#604)

## About The Pull Request

This pr ports a extremely subtle noise filter from EFN.
Extremely minor change if you ask me but its gonna add a little more
soul and thats what we love.
Jokes aside this will add to the atmosphere of the server being aboard a
run down ship in deep space.

Watch testing videos in full screen to see the difference the best, or
load up this branch to see it yourself.

Credit goes to EFN for the idea:

## How Does This Help ***Gameplay***?
More soul is always nice, Noise filter has no impact on the visual
clarity with how subtle it is.

## How Does This Help ***Roleplay***?
Minimal impact on RP.
