SPE-1963: Improve ordering of perimeters with Arachne perimeter generator

Browse source

Especially in cases when the object is composed only of 2 external perimeters and 1 or 2 internal perimeters, the order of perimeters wasn't optimal and differed from the Classic perimeter generator. That caused unnecessary long travels before the external contour was printed.

The ordering of perimeters is slightly inspired by the latest changes in CuraEngine.
