Verify WhiteIsZero invert, add Gray(1) color type
...
This was found through the fax4 decoding that is always bilevel.
No longer silently ignore an unknown color type when a photometric
interpretation requires an inversion. DICOM requires that WhiteIsZero
and BlackIsZero are only used for samples-per-pixel=1 but we do not
strictly enforce that early. Previously for the result Multiband color
we just ignored the tag which is also not right.

Return buffer layout as a struct
...
Prepares extensibility for the eventual case of supporting multi-planar
image layouts that are to be written into a multi-planar buffer as
indicated by the caller in some way (possibly not via read_*_bytes but a
method taking a wrapper around the output buffer instead). Through the
struct we can later add an indicator that can be used by the caller to
decide between methods of fetching the pixel data as appropriate.
