 [Apple Bundle ID](https://developer.apple.com/documentation/appstoreconnectapi/bundle-ids) helpers for Messages app balloons.

/// Parse the app bundle ID from a balloon bundle ID.
///
/// For example, a balloon bundle ID like `com.apple.messages.MSMessageExtensionBalloonPlugin:0000000000:com.apple.SafetyMonitorApp.SafetyMonitorMessages`
/// should get parsed into `com.apple.SafetyMonitorApp.SafetyMonitorMessages`.
///
/// # Example
///
/// ```
/// use imessage_database::util::bundle_id::parse_balloon_bundle_id;
///
/// let bundle_id = "com.apple.messages.MSMessageExtensionBalloonPlugin:0000000000:com.apple.SafetyMonitorApp.SafetyMonitorMessages";
/// let parsed = parse_balloon_bundle_id(Some(bundle_id)); // Some("com.apple.SafetyMonitorApp.SafetyMonitorMessages")
/// ```
