/// Set up a Matrix bot account by asking credentials through the terminal interactively.

/// It creates a new session, saves it for later [`login`](crate::login) use, then exits.

/// # Arguments
///
/// * `data_dir`: A directory to store the bot's state database.
///
///   Later [`login`](crate::login) calls need to use the same directory.
///
///   One directory can only store one session.
///
/// * `device_name`: Any descriptive text to distinguish this session with other sessions logged in at different locations.
