* change all usage of std.options.Option[T] to results.Opt[T] * fix broken apps and examples (to validate refactor) * removed all std/options code added for libp2p v2 migration * add broker Opt codec to persistency/backend_comm.nim * add a readValue overload for Opt[T] in tools/confutils/cli_args.nim * keep Option where required (Presto, confutils' config_file.nim) * Change generateRlnProof error handling * Fix imports
