getBBpad

 getBBpad : coordinates of bounding box with extra 'pad' pixels along x & y.

 INPUT :
       bb1: bounding box [x, y, width, height]
       ss : size of the phase image
       pad :  pixels to be added right,left, above and below of the bounding box
 OUTPUT :
       xx : array from start to end of bounding box along x
       yy : array from start to end of bounding box along y
