This changes three packages:

1. @eth-optimism/core-utils: removed event types
2. @eth-optimism/contracts: updated to latest typechain version so that better types are exported
3. @eth-optimism/data-transport-layer: uses new event types exported by the contracts package

I think @eth-optimism/data-transport-layer can pretty safely be a patch release. contracts and core-utils might have to be a minor release since this changes the API.

Changes LGTM 👍 The integration tests failed however. Looks like a flake, probably just needs to be restarted
