Force embed assets when getting the preview for the sharelinks

- enables overriding the exporttype on export
- forces the "preview" riv file that gets exported to be exported "embedded"
- allows us to handle exceptions when decoding images (more to be done here, but this at least lets us avoid crashing without being able to catch exceptions https://api.flutter.dev/flutter/dart-ui/decodeImageFromList.html)
