E2EE OCapN Federated Relays

Add relays to OCapN's capability-based networking

Spritely has been spearheading the work on creating a capability-based networking protocol called OCapN (the Object Capability Network). This network transport protocol unlocks a new way to implement peer-to-peer, distributed programming based applications. This project builds upon existing OCapN work by implementing a relay (a node that is allowed to send and receive messages from remote devices) in which all messages are end-to-end encrypted. This end-to-end encrypted relay also supports federation: users can use relays hosted wherever they wish, and the relays can seamlessly talk to each other, bridging users all over the internet while preserving their privacy and securing their communication. This relay design will also be submitted as a specification to the OCapN group, allowing for interoperable implementations across programming languages.
