Vox Sprite Update - Scarves and other Assorted Items (#3264)

## About The Pull Request
For some reason while watching Gundam I got the urge to sit down and
start doing things, so here I am.
Creates onmob_neck_vox.dmi for Vox neck items.

Adds Vox sprites for all the striped scarves in-game to Vox, as well as
Shemaghs, Cameras and the Stethoscope.
And chest-high towels.
And industrial jackets.
And updates the palette on security HUDs and medical HUDs.

## Why It's Good For The Game

Adds more supported items for the Vox, which is pretty cool I think.
Hopefully, plenty of people will appreciate the more customization
options.

chest-high towels and hazard jackets.
