- Added tcp_nat.py to handle TCP NAT, implementing the three-way handshake, data flow, and connection state management.
- Introduced udp_nat.py for UDP NAT, managing chip-initiated datagrams and maintaining flow state.
- Created integration tests in test_picow_net_bridge.py to validate the functionality of the TCP and UDP NAT implementations, including ARP, DHCP, ICMP, and DNS interactions.
