Description:
Implement support for the Telnet STATUS option to allow the client to request and receive a report on the current status of Telnet options being negotiated with the server. This option is particularly useful for debugging, diagnostics, and ensuring that both client and server have a synchronized understanding of active options.

Details:

1. Option Code: 5

2. Functionality:

   • The STATUS option allows the client to send a request to the server for a summary of the current state of negotiated Telnet options.
   • The server responds by listing all options that are currently set to "WILL", "WONT", "DO", or "DONT," providing a comprehensive view of the active Telnet session configuration.

3. Expected Workflow:

   • The client initiates a status request by sending IAC DO STATUS.
   • Upon receiving IAC WILL STATUS from the server, the client sends a STATUS SEND command.
   • The server responds with IAC SB STATUS IS followed by the list of active options, ending with IAC SE.
   • The client parses the response to confirm or adjust its internal option states as needed.

4. Acceptance Criteria:

   • The client successfully requests and receives a status report from the server.
   • The client accurately parses the server’s response, correctly reflecting the active Telnet options.
   • The status information is accessible for debugging or display purposes to ensure connection consistency.
