324e6dabf0eb51240a3006c68ce2544794f305c5 go.image/tiff: optimize reading uncompressed files from a tiff.buffer.
In case the image is read via a tiff.buffer, avoid copying the
data strip before decoding it. Remove corresponding TODO.
Speeds up reading uncompressed images (which is the common case)
and uses much less memory.
