In contrast to addGeometry(), this method does also change the geometry type of the rubberband.
The coordinate reference system of the geometry can be specified with ``crs``. If an invalid ``crs``
is passed, the geometry will not be reprojected and needs to be in canvas crs already.
By default, no reprojection is done.
