Bring back banked conveyor turns as a toggle

Update 1 removed banked conveyors turns to make designing belt network easier.
While this is great for ease of use, this means that the 2x3 spiral pattern to raise a belt by 2 or 3 levels does not work anymore.
Bring back the options to build those types of belts when specifically desired, with a build option toggle.

My factories are so much uglier now. Love the update, but this was a pretty big negative. While it may make it easier for newer players there is no reason to remove the functionality for those of us that were already happy with the system. A toggle defaulted to off is a great middle ground.

While I would love an UI toggle (both for this and retaining walls over mining designations), even a console toggle (like for aforementioned walls over designations) would still be okay.
Just... you know, some way.

I made this comment just to agree with the previous one
