Elevated pipes do not freeze on Aquilo, making them significantly stronger than just using normal pipes, ever. Yes, I know they're already stronger than normal pipes, but this somewhat defuses the difficulty of Aquilo, and I'd like to use them without it feeling unfair.

Its planned, just need to get around to making the frozen graphics.

Added a startup setting for the towers to freeze, the entity does get the blue-er shade but there are currently no custom snow graphics, and due to technical limitations the textures of the pipes in between the towers cannot be tinted in a performant manner yet so consider the startup setting an experimental opt-in.

Note that due to an engine limitation it currently does not actually prevent any fluid from flowing through it, it'll just be a visual reminder that you "should" provide it with heat, the progress of the engine support can be followed here: https://forums.factorio.com/129185 (so yea, experimental visual opt-in)
