obtaining serialized user data from the SDK

Currently, CometChat provides user data through getter and setter methods. While this works, it becomes difficult to maintain and manage the data effectively when using state management libraries such as Redux.

It would be highly beneficial if CometChat could provide user data in a serialized format (e.g., plain JSON). This would make it easier to integrate with Redux or any other state management solution, ensuring cleaner data handling and improved maintainability in larger applications.
