Rename Caption struct to CaptionMetadata

The Caption object does not actually store any text lines for the
subtitles. Instead it stores the metadata needed to display and fetch
the actual captions from the YT timedtext API.

Therefore it may be wiser to rename the struct to be more reflective of
its current usage as well as the future usage once the current caption
retrival system is replaced via InnerTube's transcript API
