Description
At present, Stamp requires a position to be given when manually instantiated. Since we allow for positions to be missing when reading/writing fits files, I think we should do the same when manually instantiating.
The default value naturally should be chosen to be `SpherePoint(Angle(numpy.nan), Angle(numpy.nan))`, the same value that gets used when reading a fits with no positions.
See attached frozen notebook for a quick illustration of the change
