Add Support for circuit Signals

[KeinNiemand]

Currently the mod does not support sending circuit network signals from one world to the other since support for that was removed. However circuit network is pretty much required for more complex logic to transfer things between servers.

For example (what I would want to use circuits for) I would like to have to LTN networks on two servers use circuits to tell server A what's provided on Server B and vice versa and then setup stations to automatically request and transfer over anything that's needed and provided on the other side, that way I could end up with something that behaves like one big LTN network, which is pretty much what I'd want so I can keep growing my base as if it where on one big map without needing to build things multiple times/segregating certain production lines to certain servers.

I suggest joining the Discord server at https://discord.gg/JhSQjMPZ and asking questions about how to implement things in the #development channel. This is something nobody plans to implement any time soon, so someone has to pick up the task from the community side.
