main ?kernel_path ~data_dir ~config ~no_sync () starts the main event-loop of the Observer, consuming the blueprints received from the EVM node endpoint, unless no_sync is true.

If init_from_snapshot and network is set, then the node will fetch and import the latest known snapshot for this network if data_dir was not already created.
