Add toggle mesecon_mode to quarry

[MCLV]

I had a little mishap when switched on the stealth node walls of my ship. It activated the quarry of the ship I was parked in front of(attached to basically)
That quarry is controlled by digiline signals and should really never be activated by mesecon.
So it would be great if a toggle could be added to the formspec to ignore it like in the supply converter.
Perhaps as a checkbox?
