SwimOS Transport Layer

This crate provides the transport layer for SwimOS (bidirectional web-socket connections over TCP sockets). It consists of:

• An abstraction over DNS to allow for the resolution of remote hosts of Swim agents.
• A networking abstraction with basic implementation for unencrypted traffic over TCP sockets.
• An optional implementation of the networking abstraction using TLS encryption.
• Bindings to use the [ratchet] web-socket library on top of the networking abstraction.
• A Tokio task to manage a bidirectional web-socket and handle communication with the core SwimOS runtime.
