Energy conduit round robin.

Description

Please test thoroughly, mainly for dupe bugs. In my testing though it seems solid (although capacitor I/O seems to show fluctuations, but when debugging it inserts fine, so probably a calculation hitch there instead).

New PR to target release branch.

Closes #337
