* refactor packages, flags, subscriptions * DRY refactor builder tests * use mockgen to generate mocks * update README * MODE=statediff no longer needed for unit tests * simplify func names, clean up metrics * move write params to service field * sql indexer: confirm quit after ipld cache reset prevents negative waitgroup panic * don't let TotalDifficulty become nil * use forked plugeth, plugeth-utils for now
