Revert "Makes TEG Circulator bidirectional" (Citadel-Station-13#6786)

Reverts Citadel-Station-13#6764

It literally does not work as advertised. It doesn't work at all.
There's only one output side, it always puts into the output side. It
can take from the output side, and then it puts it back into the output
side. This is a non-functioning PR. Test your PRs properly.
