docs: Adds an embedded image (attachment type) to the email message and generates the necessary {@link DataSource} with
  the given byte data. Then delegates to {@link #addEmbeddedImage(String, DataSource)}. At this point the
  datasource is actually a {@link ByteArrayDataSource}.
  
  @param name The name of the image as being referred to from the message content body (eg.
  '&lt;cid:signature&gt;').
  @param data The byte data of the image to be embedded.
  @param mimetype The content type of the given data (eg. "image/gif" or "image/jpeg").
