  windowscodecs/tiff: Skip frames marked with SUBFILETYPE(0x1).
  
  This is important for RAW formats that use TIFF container, but mark
  directories as 'reduced-size'. Those files should be processed with
  appropriate RAW decoder, instead of displaying auxiliary frame with
  the TIFF decoder.
  
  Unfortunately libtiff skips old tag OSUBFILETYPE == 0xff,
  it's not available via TIFFGetField() and SUBFILETYPE is not synthesized
  from it. On Windows both tags have the same effect on frames
  being skipped by the decoder.
