feat(model): kernel a82f17d — MASSPROP from B-rep, curved OFFSET/FILLET

- Pins: codec 8189f83, kernel a82f17d, graph d3558bb (all manifests and
  the python plugin lock).
- MASSPROP reports volume, centroid, inertia, products, radii of
  gyration and principal moments of 3D solids and bodies from their
  B-rep (exact where analytic, else from a fine mesh).
- OFFSET of ellipses and splines through the kernel's curve offset.
- FILLET between circles, ellipses and splines through the kernel's
  curve-curve fillet, trimming arcs and open splines to the tangents.

The kernel bump brings the DWG ACIS audit fixes: slices, booleans and
press/pull on cones, slanted cylinder sections, survey coordinates,
spline walls and touching parts.
