Adjust the geolocations of the SR pixels

With SR, we refer to precipitation radars based on space-born platforms such as TRMM or GPM.

The sr_xy coordinates of the SR beam footprints need to be in the azimuthal equidistant projection of the ground radar. This ensures that the ground radar is fixed at xy-coordinate (0, 0), and every SR bin has its relative xy-coordinates with respect to the ground radar site.
