* Replace assetDataUtils with DevUtilsContract wherever possible
Does not replace from @0x/instant and some @0x/order-utils uses
* Add revertIfInvalidAssetData to LibAssetData
This is needed to replace `assetDataUtils.decodeAssetDataOrThrow`.
Because it's used in packages and not only contracts, we should wait
to deploy the updated contract so we can update `@0x/contract-artifacts`,
`@0x/abi-gen-wrappers`, and `@0x/contract-wrappers` first.
* remove usages of signatureUtils
* fix test for optimised encoding
* refactor @0x/contracts-integrations
* update changelogs
* Move @0x/contracts-dev-utils from devDependencies to dependencies
It is exported as part of the package
* introduce --debug option to abi-gen and remove debug functions from @0x/abi-gen-wrappers
* make evmExecAsync protected; ignore deployedBytecode in doc comment
* trim deployedBytecode so it's undefined unless a contract has pure functions
* remove validateAndSendTransactionAsync
* Create `AwaitTransactionSuccessOpts` and `SendTransactionOpts` types
* Remove duplicate types `IndexedFilterValues`, `DecodedLogEvent`, `EventCallback` from `@0x/base-contract`
