Implement the recent EPUB 3.3 clarifications about data URLs: - they do not represent publication resources - they cannot be used in the package document (neither in `item` nor `link`) - they are still subject to foreign resource restrictions (must be a CMT or used where an intrinsic fallback is provided) see https://github.com/w3c/epub-specs/pull/2494
