PDF metadata: When updating the XMP metadata in PDF files, compress the metadata written to the PDF. This is particularly useful when the PDF file has an existing XMP metadata block with very large amounts of data in it. Fixes #1341549 [Embed Metadata for PDF consistently adds 0.5MB to book size](https://bugs.launchpad.net/calibre/+bug/1341549)
