docs: Skips the current MPEG frame. This method can be called after a valid MPEG header has been retrieved using {@code nextFrame()}. In this case the underlying stream is advanced to the end of the associated MPEG frame. Otherwise, this method has no effect. The return value indicates whether a frame could be skipped.
  
  @return <b>true</b> if a frame could be skipped, <b>false</b> otherwise
  @throws IOException
