Added printing of TIFF meta data via TIFF.toString().
Added tracking of ImageFileDirectory file offset. Adding printing of this
offset in the metadata.
Fixed bug that was causing some values to be read as negative.  Since Java
does not have unsiged types reading a short, for example, whose high bit
is set will cause the result to be negative.
In ImageFileDirectory initialize imageDescription member to the empty
string. Add code to shorten the description returned by toString() if it is
too long. Remove newlines from printed description.
Changed implementation of RegularTIFFParser.getOffsetOfFirstIFD() to use
SeekableDataInput.readInt() to SeekableDataInput.readUnsignedInt().
Added compression types JPEG2000_YCbCr (33,003) and JPEG2000_RGB (33,005)
to compression enum.
Add parsing of PlanarConfiguration tag.
Added parsing of TIFF tag Predictor.
