This patch adds a 'Intersecting Edges' output with a boolean selection that only gives you the new edges on intersections. Will work on a couple of examples next, this should make some interesting effects possible (including getting us closer to the "bevel- after-boolean-usecase") To achieve this, a Vector is passed to `direct_mesh_boolean` when the iMesh is still available (and intersecting edges appended), then from those edge indices a selection will be stored as attribute.
