f594c3aad5 go.image/tiff: initial support for writing TIFF images 
The basic functionality works. Features to add in future CLs:

- compression
- fast paths for image formats that can be directly expressed in TIFF,
  such as RGBA, NRGBA and maybe Gray and Paletted.

324e6dabf0 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.
