/// Edited messages include `message_summary_info` that contains a dictionary
/// with message body part data, including [`typedstream`](crate::util::typedstream)-encoded
/// edit history. The order of entries in the edit history represents the order

/// ## Message Body Parts
///
/// - `otr`: dictionary of message part indexes.
/// - `rp`: list of unsent message part indexes.
/// - `ec`: dictionary of edited message part indexes to edit history arrays.
/// - Each `ec` item stores `d` (edit timestamp) and `t` (edited
///   `attributedBody` typedstream).
