path identifier, these should identify individual paths
object_

Details
This function exists as a special-case for non-format input for PATH0(). It's expected there
are columns x, y, and optionally object_, subobject_, and path_. These correspond to
names in sfheaders, multipolygon_id, polygon_id, and linestring_id. (subobject is optional if
not multipolygon).
