Request: Allow reversing the pin order (e.g., start at 8 and count down to 1, top-to-bottom) for crossover cables

[DeflateAwning]

It would be very helpful to be able to arrange a wiring diagram for a crossover cable (e.g., 1->8, 2->7, 3->6, etc.) by flipping the order of the labels on one connector.

I propose that this feature could be added by having a pins_descending: bool setting added to the connector (and wire) definition block.

Having this feature work automatically could be cool, but would probably be best to start with it being set explicitly.

This seems to be a duplicate of #427.

Neat, thanks! My new request is that this gets added as an example in the examples! I could probably help submit a PR for that at some point!
