I;16 images are little endian, not native endian
uint16 varies from platform to platform, <u2 is spefific
Tests for endian issues in decoding 16bit tif images
MM and II 16 bit integer tiffs unpack properly using libtiff on bigendian platform

Tag issues with libtiff -- Need to parse the tuples for the ifd and the im.ifd. getattr + default for the im.ifd instead of silent try/except
