Version 0.2.0

Implemented a new IKEv2 (L3) VPN mode.

Version 0.1.0

• Switched to rustls + ring for TLS connections, as this combination appears to be more actively maintained than native-tls and supports TLS 1.3.
• Detect loopback connections and drop them to prevent single-threaded Tokio from locking up.
• A few small code changes/refactorings.

Version 0.0.1

Initial release.
