Constructs a multi-point from a list of point values. All of the supplied point values must have the same SRID, and the multi-point
is constructed with this common SRID.
All of the supplied point values must have the same answer for Is3D and IsMeasured. The multi-point is 3D if all of the point
values are 3D, and the multi-point is measured if all of the point values are measured.
