Awesome gem! 🏆

A method to access image data would be useful. For example image dimensions, and perhaps exif data too.

For VIPS, something along these lines should work.

def dimensions
  { :width => vips_image.x_size, :height => vips_image.y_size }
end

But may make more sense with a general image_properties method, that would return a hash with more than just width/height.

What do you think?
