LemonInTheDark 4d1e34322f Macros multi-z code, removes the false premise of manual offsets (#76248) 
## About The Pull Request

[Removes the pretense of relative multiz
levels](0293fdc2bd)

Our multiz system does not support having a z level that is only
connected one way, or which goes down backwards or anything like that.

That's a fiction of the trait system, the actual backend has never
really supported this.

This pr removes the assumptions we were making backend around this, and
uses that to save cpu time.

I am also converting multiz_levels from an assoc list to a pure one,
which saves significantly on access times and cleans up the code
somewhat.

Also I'm making the get_below/get_above procs into macros, for the sake
of cpu time.

[Converts the starlight disease to use BYOND's directional defines
instead of our
own](7d698f02d9)

To some extent spurred on by
https://github.com/DaedalusDock/daedalusdock/pull/298, tho it was known
before

## Why It's Good For The Game

Faster multiz code, faster init, etc etc etc

/**
* playsound is a proc used to play a 3D sound in a specific range. This uses SOUND_RANGE + extra_range to determine that.
*
* source - Origin of sound.
* soundin - Either a file, or a string that can be used to get an SFX.
* vol - The volume of the sound, excluding falloff and pressure affection.
* vary - bool that determines if the sound changes pitch every time it plays.
* extrarange - modifier for sound range. This gets added on top of SOUND_RANGE.
* falloff_exponent - Rate of falloff for the audio. Higher means quicker drop to low volume. Should generally be over 1 to indicate a quick dive to 0 rather than a slow dive.
* frequency - playback speed of audio.
* channel - The channel the sound is played at.
* pressure_affected - Whether or not difference in pressure affects the sound (E.g. if you can hear in space).
* ignore_walls - Whether or not the sound can pass through walls.
* falloff_distance - Distance at which falloff begins. Sound is at peak volume (in regards to falloff) aslong as it is in this range.
