ENH: add a new support style "Tree Organic"

Browse source 
Add a new suport style "Tree Organic" from Prusa, as organic support is
faster and seems more strong in some cases. Thanks to Prusa.

Feature detection including sharp tail, small overhang, long cantilever,
are still kept.

Known issue: first layer support path may go outside build plate.
