Add camera mod to diagnostic hud

[ArZarLordOfMango]

About the PR

Added camera mod to diagnostic hud. That allow you to look at the world as an AI (they don't allow you to look through walls, just give you a “noise” effect). You can also turn them on and off by action. They're can researched in the experimental branch.

Why / Balance

Playing as an AI, sometimes it can be difficult to explain where to put the cameras to get a better field of view. Especially if you don't know the map.

it'd be funny of the sprite was like a blocky VR headset

[Everturning]

i love this because it both buffs traitors and AI and thats hilarious to me

[Everturning]

wait the sprite is called just "camera.rsi" I'm in no way a dev but that does seem like it'd cause issues

[lzk228]

would be neat to make not AI overlay, but like make visionless zone darkened or something

[HerCoyote23]

I'd recommend you change the item description to something like:
Advanced visor which displays camera view ranges. Useful for working with the Station AI.

as the current:
Advanced glasses are designed to look like through cameras. Useful for working with Station AI.

is grammar-wise pretty rough.

Hey, I brought this up for maintainer discussion. Instead of making this its own item, could you add this functionality to the diagnostic HUD instead?

[slarticodefast]

Did some more testing and found a bug:
Take the glasses into your hands, activate them and drop them. You will keep the overlay.

Also the shadows look a little weird sometimes when there is static, but I'm not sure how this could be prevented ecxept by allowing you to look through walls (assuming there is a camera), which would be quite powerful.
