feat!: lazy stream routing protocol

- PubSub and the block swap protocol has been improved with a lazy stream protocol that allows you only to have knowledge about peers you talk with and no-one else.
- Routing is made more efficient by tracking delivery times
- Redundancy parameters can be used to make delivery more resiliant to unreliable networks
