Pull Request Overview

This PR removes SendTimeout and ReceiveTimeout options from the TcpSocket library, implementing a more efficient async socket handling approach using IValueTaskSource pattern instead of TaskCompletionSource.

• Refactored Sender and Receiver classes to inherit from SocketAsyncEventArgs and implement IValueTaskSource pattern
• Removed timeout-related code from send/receive operations
• Updated package references from Microsoft.Extensions.Options.ConfigurationExtensions to Microsoft.Extensions.Options
• Modified buffer handling in extension methods to use ArrayPool instead of MemoryPool
