This is a major release. The project name has changed from sentinel-visor to lily, the binary
produced when building the project has changed from visor to lily, and all lenses have been removed.
This means lily will cease to work with the lotusAPI lens, CAR-file lens, and Repo lens. Henceforth, Lily
will run as a daemonized process capable of both syncing and processing the Filecoin blockchain.
