Wrong image size reported for Fuji raf

[astippich]

Exiv2 reports wrong image width and height for Fuji Raf files. Looking at the code, this is because it returns "Exif.Photo.PixelXDimension"/"Exif.Photo.PixelYDimension" for width/height, which is obtained from the embedded JPEG, which is not the size of the raw image.

Determining the size of the RAW image in a RAF file is difficult. Models are inconsistent in how they store this information. It is possible to obtain a consistent size for the image including black borders, but difficult to consistently deduce the final cropped image size.

Ah. Iliah Borg has just informed me that FujiFilm RAF tag 0x0111 gives the raw image cropped height and width as two 16-bit integers. I'll add decoding of this tag to ExifTool, and use it in the Composite ImageSize determination.
