## About The Pull Request
Revival of #92846, without which I would have no idea how to do this
Adds a new proc within `/datum/atom_hud` that changes what Z level huds
an atom is seeing without changing what Z level that atom's own hud
exists on, and hooks it into the new `COMSIG_LIVING_LOOK_Z_CHANGE`, sent
by `/mob/living/on_look_z_level_change()`, which is called when a mob
looks up, stops looking up(not when it looks down, it doesn't need to),
or by any z level change done by an `/eye/` that's just the window for
an actual mob(camera consoles, AI eye).
## Why It's Good For The Game
