Add fast Go image.Image interop: ToGoImage and NewImageFromGoImage (#489, #480) (#504)

ToGoImage() converts a vips image directly to a Go image.Image by
reading raw pixel data, bypassing the encode/decode round-trip that
ToImage() uses. This is significantly faster for interop with other Go
image libraries.

NewImageFromGoImage() creates an ImageRef from any Go image.Image by
normalizing to NRGBA and using vips_image_new_from_memory_copy for
GC-safe pixel data transfer.
