Update exposed wires

[oosyrag]

I'd like to update the look of exposed wiring.

Romex, generally found in house wiring -

Or metal clad, common in commercial settings -

At the least the wire should be twisted a little nicer, wire for conduits, without the conduit -

I also think wires could benefit a lot from being neighbor aware/multitile support, instead of a cross for every tile.

I did just test to make sure but I'm pretty sure the last line isn't possible atm bc exposed wires are an appliance which are vehicle parts under the hood and vehicle parts don't support multitiles afaik. I'm not sure whether it would be best generally to add them as cosmetic variants like vehicle parts proper or whether adding multitiling would be ideal (or some cursed hybrid where the multitile rules dictate which cosmetic variant should be shown and you can't change it manually)
