Inject JavaScript bundles and Readium CSS with WebPubs

[mickael-menu]

JavaScript and Readium CSS were injected only for publications marked explicitly as EPUB. Instead, this will inject it for any HTML resource.

Note: I'm not yet sure this should be the default behavior for WebPubs.

If you want to support pagination / user styles with a Readium Web Publication Manifest, add the following in the metadata:

{
  "metadata": {
    "conformsTo": "https://readium.org/webpub-manifest/profiles/epub"
  }
}

Alternatively, you can add it dynamically while opening the webpub with the Streamer with:

streamer.open(...,
    onCreatePublication = {
        manifest = manifest.copy(
            metadata = manifest.metadata.copy(
                conformsTo = listOf(Publication.Profile.EPUB)
            )
        )
    }
)
