 abstract Try<ContentProtection.ProtectedAsset, Publication.OpeningException> open(PublicationAsset asset, Fetcher fetcher, String credentials, Boolean allowUserInteraction, Object sender)
```
    Attempts to unlock a potentially protected publication asset.
    The Streamer will create a leaf fetcher for the low-level asset access (e.g. ArchiveFetcher for a ZIP archive), to avoid having each Content Protection open the asset to check if it's protected or not.
    A publication might be protected in such a way that the package format can't be recognized, in which case the Content Protection will have the responsibility of creating a new leaf Fetcher.
