v0.9.0

Breaking Changes

• Updated to automerge@0.8.0

Fixed

• A bug where locally unavailable documents sent by peers with an announce
  policy set to false would be marked as unavailable

Added

• TcpDialer::new which takes a Url parameter, rather than a host and a port
  or a socket address.
• Repo::dial_tcp() to simplify construction of TcpDialer.
• Allow documents syncing over the TCP transport to be up to 8gb size instead
  of Tokio's default 8mb frame size
• Exposed receiving ConnectionHandles via accept(). Users can now subscribe
  to an events() stream directly on the handle, or await for
  handshake_completed().
