dce36e0074 Add normalize() for simple histogram stretching 
Available as normalize() or normalise().
Normalization takes place in LAB place and thus should not change any
colors.

Existing alpha channels are preserved untouched by normalization.

This removes the custom image fingerprinting code and uses the libvips
is_a_buffer() infrastructure instead.
