This PR adds transport key functionality to the mesh packet system, enabling packet authentication using region-based transport codes. The implementation matches the C++ MeshCore firmware protocol, ensuring cross-platform compatibility.
Key Changes:
Introduced transport key generation and transport code calculation utilities
Extended packet structure to support optional 4-byte transport code fields for TRANSPORT_FLOOD and TRANSPORT_DIRECT route types
Added helper methods to identify packet routing characteristics

This PR implements control packet handling for mesh node discovery, adding a new packet type (0x0B CONTROL) and handler infrastructure to enable nodes to discover each other on the mesh network via zero-hop broadcast packets. - Added PAYLOAD_TYPE_CONTROL (0x0B) constant and corresponding packet type mapping - Implemented ControlHandler for processing discovery request and response packets - Added create_discovery_request() and create_discovery_response() methods to PacketBuilder - Provided two example scripts demonstrating discovery functionality

This PR introduces authentication support for anonymous login requests and adds Listen Before Talk (LBT) feedback metrics to the mesh network protocol. Clients can now securely authenticate using encrypted anonymous requests, and the radio layer provides detailed transmission feedback for improved network behaviour and diagnostics. Key Changes Anonymous authentication Added LoginServerHandler to process encrypted ANON_REQ packets Implements password validation and ACL enforcement for anonymous clients Protocol request handling Added ProtocolRequestHandler to manage REQ / RESPONSE protocol messages in a unified flow LBT feedback metrics Extended the SX1262 radio driver to collect LBT metrics, including: Backoff delays Channel busy detection Airtime usage Text message handling Enhanced text message handler to support CLI command messages via the txt_type field CLI messages do not require ACKs, reducing protocol overhead Bug fix Improved PI initialisation reliability for the radio chip by adding a required startup delay, resulting in faster and more stable initialisation

Support for anonymous login requests and adds Listen Before Talk (LBT) feedback metrics to the mesh network protocol. Clients can now securely authenticate using encrypted anonymous requests, and the radio layer provides detailed transmission feedback for improved network behaviour and diagnostics.
Key Changes
Anonymous authentication
Added LoginServerHandler to process encrypted ANON_REQ packets
Implements password validation and ACL enforcement for anonymous clients
Protocol request handling
Added ProtocolRequestHandler to manage REQ / RESPONSE protocol messages in a unified flow
LBT feedback metrics
Extended the SX1262 radio driver to collect LBT metrics, including:
Backoff delays
Channel busy detection
Airtime usage
Text message handling
Enhanced text message handler to support CLI command messages via the txt_type field
CLI messages do not require ACKs, reducing protocol overhead
Bug fix
Improved PI initialisation reliability for the radio chip by adding a required startup delay, resulting in faster and more stable initialisation
