The switching station and supply converter only semantically connect to
cables in particular directions. Make them visually connect only in
the matching directions. This is done by special-casing in the cable
update logic. If more irregular items arise in the future, or the
existing items start to need facedir logic, this should be generalised
into something like the connect_sides system for pneumatic tubes.
the first-seen tier for which the machine was registered. So the
switching station, which is uniquely registered for all tiers, would
only visually connect to LV cable when placed, not to MV or HV cable.
(It would function nevertheless, and cable would connect to the switching
station if placed later.) Change to consider all tiers. Incidentally
avoid a gratuitous iteration through all registered machines.
