v0.2.3

Client Module Enhancements:
- Added a new download function in the client module, allowing the client to receive files over an established connection.
- Improved documentation for client module functions, detailing usage and functionality.

Request Upload Update:
- Simplified the Request::Upload structure by removing PathType as a required field. The file transfer protocol now determines the path type, improving clarity and flexibility.
Connection Management:
- Updated the client to store the TCP connection in an Arc<Mutex<Option<TcpStream>>> to enable safe concurrent access across async contexts.
- Modified send_request function to accept a Request object, streamlining request handling.

Resolved Client dyn Error Handling:
- Switched to anyhow::Error for more flexible error handling in the client, addressing issues with dyn Error.
Server Shutdown Signal:
- Made the stop signal public and created a new stop_server function, enabling cleaner shutdown management.

This release includes fixes for issues raised in #54 and enhances the client’s transfer capabilities.

Added support for file upload and download functionalities.
Introduced directory transfer capabilities, allowing users to send entire directories along with their contents.
