Create smaller supports in problematic areas with established strategies
Completely remove the concept of CompactBridge.
Replace it with Heads having the same back radius as front radius.
Try to apply the same rules for mini supports as in the route_to_model step.
Increased accuracy of bridge_mesh_intersect shot from support points
Refining mini support integration
