lazy image loading shouldn't read the entire .xls file (tdf#124828)
b11188835d3b87cd changed msfilter to use
GraphicFilter::ImportUnloadedGraphic() to lazy-load images
from the document. However, that function in some cases simply
reads the entire rest of the passed SvStream, which in this case
is the entire .xls file. And the document from tdf#124828 is ~50MiB
and contains ~4000 images => 100+ GiB memory required.
