* Export artifacts and addresses from abi-gen-wrappers * only export addresses, not artifacts * abi-gen-wrappers no longer accept ContractAbi as constructor param ABI is now hardcoded when wrapper is generated * remove unused imports * remove unused import * changes after review * fix method ordering * update constructor args * prettier * statically enumerate ABI properties * remove abi-gen-wrappers generated-wrappers from prettierignore * add template for recursive components * add `indexed` field for EventParameter * prettier * update known-good wrappers with ABIs and fix Python ABI loading * remove generated-artifacts and update gitignore
