- fixed ugly bug, the call of TIFFGetField() is very strange and returns
  matches even if tags actually does not exist. The reason of this problem is,
  that the function does not scans the existance of tags in IFD, but in internal
  libtiff-structure. Therefore the functions TIFFGetAllListCount() and
  TIFFGetAllTagListEntry() are replaced by completely rewritten
  TIFFGetRawListCount() and TIFFGetRawListEntry() using the file descriptor of
  given image and very low-level functions to parse the first IFD of TIFF-file,
  instead.
