/**
 * Dynamically injects a saga, passes component's props as saga arguments
 *
 * @param {string} key A key of the saga
 * @param {function} saga A root saga that will be injected
 * @param {string} [mode] By default (constants.RESTART_ON_REMOUNT) the saga will be started on component mount and
 * cancelled with `task.cancel()` on component un-mount for improved performance. Another two options:
 *   - constants.DAEMON—starts the saga on component mount and never cancels it or starts again,
 *   - constants.ONCE_TILL_UNMOUNT—behaves like 'RESTART_ON_REMOUNT' but never runs it again.
 *
 * Deprecated - this HOC will be deleted when React 17 is released. Migrate to hooks and useSaga before then.
