feat: ranger receiver

[Rjected]

Motivation

The ideal configuration of ranger allows for multiple relay nodes which are highly connected in the peer to peer network. Some of these relay nodes will learn about certain transactions first, with others receiving those transactions in the peer to peer network much later.

A receiver node that connects to all ranger relay nodes should be implemented, ideally providing a Stream of transactions after connecting to the ranger nodes.

Design

A minimal viable receiver would need:

• [ ] Static configuration file for incoming ranger nodes.
• [ ] Deduplicating streams
