ImageJ 1.x TIFFs have slice labels which can indicate alternate orderings of the lut. We should read and either:

a) store the information in the MetaTable
or
b) rearrange the color tables as indicated.

Upon further investigation it looks like there are problems with how the TIFFParser is storing the ImageJ1 comment and how it is retrieved here.

There are actual luts stored in the ImageJ comment and they are not extracted correctly (stored as a short array in the IFD)

TIFFFormat: parse IJ1 color table
1d01104 
ImageJ 1.x can write 8-bit lookup tables in the TIFF ImageJ 1.x comment.
These are not properly read when retrieved from the IFD as a String.
They need to be parsed by reading the metadata tags and determining the
actual offsets and lengths.

We now parse and use the IJ 1.x color table if needed.

Closes #202

NB: See also #203 for future plans
