Techpack Tubelib

When Terumetal is loaded alongside Techpack's tubelib, an additional upgrade will become available: the Tube Support Upgrade. This upgrade is simply made by combining an Upgrade Base with a single tubelib Tube.

While placed in an upgrade slot of a machine with input/output slots, that machine will accept and provide items to and from those slots through tubes as expected. So when a pusher is placed against a machine, items from its output will be pulled out into a tube, and when a tube ends at a machine items pushed through it will go to the machine's input.

Note that due to technical limitations, tubes will always appear to connect to a machine, but tubes and pushers will only function properly when a Tube Support Upgrade is in the machine.
