Version 8.0.0 - New peer discovery, built-in persistence

This release improves the speed and reliability of dat-js while simplifying the developer experience.

Added:

• discovery-swarm-web support
  • Will eventually support extensions like datPeers
  • The gateway can no longer see the data it's proxying so you can worry less about private data
• New persist flag that will automatically set random-access-web as the storage layer so you can save data for offline use and page reloads
• Everything works out of the box with the default gateway

Removed:

• Got rid of the repo abstraction and used hyperdrives directly
