New Nodes

Polygonjs now supports exporting several file formats:

• sop/CADExporterSTEP: exports STEP files, which can be generated from the CAD nodes.
• sop/exporterGLTF: exports GLTF (this nodes already existed, and was named sop/exporter)
• sop/exporterOBJ: exports OBJ
• sop/exporterPLY: exports PLY
• sop/exporterSTL: exports STL
• sop/fileUSDZ: imports USDZ

Improvements

• sop/boolean: add param to keep only intersection edges
• sop/CADGroup: highlight currently selected edges/faces
• sop/clip: allow preserve of below and above primitives

Bug Fixes

• sop/merge: fix bug where standard object properties would not be preserved by sop/merge in compact mode
