babl-palette: improvements toward palette accuracy

For working at acceptable performance with large indexed images, it is
recommended to run with BABL_TOLERANCE=0.0385 or highger set in the environment
when launching GIMP, this permits using a hashtable based optimization that
still isn't accurate enough according to babl-expectations.
