ENH: improve auto-arrange in several ways

Browse source 
1. reduce expansion of exclusion regions
2. expand extrusion calib regions to let them touch bed boundary, to
   greately simplify auto-arranging with avoidance option on
3. improve dist_for_BOTTOM_LEFT to allow objects be put left to
    exclusion regions temporarily
4. improve on_preload for better handling objects around exclusion regions.
5. improve debug tools
6. fix a bug with wipe tower estimation (don't estimate if wipe tower is
    explicitly disabled)
7. use larger y-overlap threshold to estimate rod height confliction
   better in per-object print ordering (now we use half the clearance
   radius)
