Tiff: added isBigEndian and getDirectoryOffset methods to the class
* scripts/io/Tiff.m: added isBigEndian and getDirectoryOffset methods
to the class.
* libtinterp/corefcn/tiff.cc: added __tiff_is_big_endian__ and
__tiff_get_directory_offset__ as internal functions for isBigEndian
and getDirectoryOffset repectively.
* scripts/image/private/__tiff_imfinfo__.m: used the two new methods
to get the corresponding info fields.
