ENH: Add generate_pole_figure program for .ang and .ctf files

Reads an EBSD data file (.ang or .ctf), groups orientations by phase,
and generates 3 pole figure TIFF images per phase using the default
pole figure directions for each crystal symmetry class. Includes
stereographic projection annotations (great circles, Miller indices).
