NewPipe

-Supply and scrubber pipes can be run in parallel without connecting to each other
-Supply pipes will only connect to supply pipes, vents and Universal Pipe Adapters(UPAs)
-Scrubber pipes will only connect to scrubber pipes, scrubbers and UPAs
-Supply and scrubber pipes are offset along the x and y axes to prevent sprite overlap
-UPAs will connect to regular, scrubber and supply pipes, as well as anything else that connects to a regular pipe. UPAs will be used to interface between the supply/scrubber loops and atmos
