feat(editor): a switch path can be a chain of pieces: the attributes pieces1 and pieces2 keep the parts of each path after the classic bezier, which stays as the approximation older versions read and log the attributes as unknown; the simulation drives, draws and maps a path along its pieces by distance, pieces that don't join the ends of the path are reported and the bezier used; the catalogue Rz switches get the diverging path as the arc of their radius and the straight after it, moving, rotating and mirroring a switch carry the pieces, reshaping a path by hand drops them; self-test commands switchpieces and switchbreak
