Refactoring FDM support spots generator to use Z-Graph (#11)

Browse Source 
* import updates from curling avoidance branch

* fix compilation issues

* Refactoring FDM support spots generator to use the new Z-graph built during slicing

* fix local issues bugs

* fix bugs, add new filter for too short extrusions

* fix bugs with nonexistent weakest area

* Use links of Z graph after fix, format the code

* remove unnecesary includes
