Implement Telnet STATUS Option Support

[mystiker]

Description

This pull request introduces support for the Telnet STATUS option, allowing the client to request and receive a report on the current state of negotiated Telnet options with the server. The STATUS option enhances debugging and diagnostics by providing visibility into the active Telnet session configuration. This implementation is based on RFC 859.

Key Changes

• Added handleStatusOption function: Manages the STATUS option negotiation by handling the DO, DONT, WILL, and WONT commands related to the STATUS option.
• Subnegotiation support: Upon receiving WILL STATUS from the server, the client sends a STATUS SEND command, prompting the server to respond with its current configuration of active options.
• Enhanced option handling via dedicated handler functions for each negotiation command, including handleStatusDo, handleStatusDont, handleStatusWill, and handleStatusWont.

Acceptance Criteria

• The client can initiate a status request and accurately receive a response.
• The response is correctly parsed, allowing the client to reflect the active Telnet options.
• Status information is available for debugging and display purposes, helping maintain connection consistency.
