Use this when you want to know how many images of what formats are in a PDF
but you don't need to render the images (e.g. for OCR).  This is far
faster than {@link #extractInlineImages} because it doesn't have to render the
images, which can be very slow.  This does not extract metadata from
within each image, rather it extracts the XMP that may be stored
external to an image in PDImageXObjects.
