Will 397d569b37 Atmos Pipe Improvements (#19478) 
* pumps use their layer to connect pipes visually

* connectors for supply and scrubbers

* pump dmi stuff

* fixed volume pump dmi

* Vents support multiple connection types

* prevent multiple pipes attaching to the same side

* old code

* prioritize linking already connecting pipes

* constructable pressure tanks

* tank icon fix

* color fix

* fixes

* multiple connection universal pipes

* possible network fix

* buh buh

* tanks no longer go invisible

/*
Every cycle, the pump uses the air in air_in to try and move a specific volume of gas into air_out.
node1, air1, network1 correspond to input
node2, air2, network2 correspond to output
Thus, the two variables affect pump operation are set in New():
air1.volume
This is the volume of gas available to the pump that may be transfered to the output
air2.volume
Higher quantities of this cause more air to be perfected later
but overall network volume is also increased as this increases...
