don't attempt to save large XMP to JPG
...
jpeg_write_marker() with some libjpeg versions will throw a fatal
error with large chunks.
To write >64kb XMP it you need to parse the whole XMP object,
pull out the most important fields, code just them into the main
XMP block, then write any remaining XMP objects into a set of
extended XMP markers.
http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart3.pdf
Instead, just warn and skip large XMP blocks.

istiff tests first dir rather than magic number
...
We were testing for TIFF by checking the magic number at the head of the
file. However, formats like ARW are TIFF-like without being TIFF, and
will not load with tiffload.
Instead, try reading the whole of the first directory. This is enough to
stop tiffload trying to load files where it will simply fail
immediately, and make libvips fall back to eg. imagemagick.
