operations: Add gegl:rgbe-load and gegl:rgbe-save
Add a radiance (rgbe) HDR image format reader and writer. Implements reading of uncompressed and new-rle scanlines, and writing of uncompressed scanlines. The RGBE load and save code is put in a separate library so it's easy to move out of the GEGL tree or replace with something else. Also add test cases for both loading and saving.
