Allow specifying the vertical longitude for polar stereographic projection

The EPSG codes do not allow us to specify the vertical longitude for polar stereographic projections. For both EPSG:32661 (polar north) and EPSG:32761 (polar south) the vertical longitude is 0. So we go for a non-standard solution and allow encoding the vertical longitude into the EPSG code as follows:

polar north: EPSG:32661:vertlon
polar south: EPSG:32761:vertlon

where vertlon is a number in the range of [-180, 180]
