Pubsub channel to report data-root updates in

[icidasset]

The data-root DNSLink always points to content that is available on the gateway. To get faster updates, we can create a pubsub channel to report updates to.

However, w’re going to be increasingly relying on pubsub for future features. We can then push IPNS updates on a channel (“experimental IPNS-over-pubsub”) Due to the nice properties of FS versioning, online users can then see “hey there’s new stuff on top of that!” Before we’ve downloaded it Which also solves for offline/mesh/P2P use cases
