Add media.ccc specific parsing of recordings
Instead of pushing the `media.ccc` recordings straight into the StreamExtractor straightjacket (which does not really provide the correct API for handling the semantics of the media.ccc data), we parse into an intermediate structure first that contains all relevant information about the different streams. This is required for correct handling of the different languages.
