`--self-contained`: don't incorporate elements with `data-external="1"`.
You can leave an external link as it is by adding the attribute
data-external="1" to the element. Pandoc will then not try to
incorporate its content when `--self-contained` is used. This is
similar to a feature already supported by the EPUB writer.
Closes #2656.
