Description
How to get hull's halfedges ? Is there anything to get them directly or must I check all edges around hull's points ?
I need this to close the triangulation on a sphere. The last triangles are made with a pole in sterographic projection connected to each hull's edge. This pole/point is removed before running delaunator then added after and so all new triangles with this new point.
hull give points but hulltri, hullhash, hullnext and hullprev are not related to hull's actual edges.

Research direction
Start by examining how the hull, hulltri, hullhash, hullnext, and hullprev data are represented and related to the triangulation. The issue does not name a source file or test, so locating the relevant hull-handling entry point is required first. Done would be a supported way to obtain the hull's halfedges for the described spherical-closing workflow.
