-     public class ID3v23FrameBodyGeneralEncapsulatedObject
      extends ID3v23FrameBody

  A general encapsulated object frame body is associated with an ID3v2.3 `GEOB` `frame` which is used to embed a file in the .mp3 file. The file may be of any type. This is a generalization of the `attached picture` frame which only allows image files to be embedded in the .mp3 file. The general encapsulated object frame body contains the following fields:

  General Encapsulated Object Frame Body Fields
  | Field | Description
  --- | --- | ---
  1. | `encoding` | character set used to `encode` the filename and description fields.
  2. | mimeType | the MIME type and subtype for the encapsulated object. This field is optional and may be left blank.
  3. | filename | name of the file from which the encapsulated object was read from. This field is optional and may be left blank.
  4. | description | description of the encapsulated object.
  5. | object | raw binary data of the encapsulated object.

  There may be more than one general encapsulated object frame in an ID3v2.3 `tag`, but only one with the same description field.

      - empty filename
      - "encapsulated object" as the description
      - 0 byte object

        `filename` - filename that held the encapuslated object on disk.
        `description` - description of the content.
        `object` - raw binary data of the encapsulated object.
