• Client: Added a Disconnect request as poison pill for stopping the client service and to release the underlying transport
• Added utilities to share a single Modbus context within a thread for communicating with multiple devices
• Added utility functions to disconnect and reconnect stale connections after errors
• Minimal Rust version: 1.34.0

Potential breaking change

Extending the Request enum with the new variant Disconnect might break existing code. This variant is only used internally within the client and will never be sent across the wire and can safely be ignored by both clients and servers!
