Collapse the two variations of `VorbisUtil.buildMetadata` into a single method called `VorbisUtil.parseVorbisComments` that only takes a list of vorbis strings, compared to previously where it would take strings and picture frame instance. Any code that relied on the old signature now either concatenates picture frames and vorbis comments or copies vorbis comments into an existing metadata instance.
