Contributions summary:Marius primarily contributed to the core logic of the Interchain Security project. Their work includes the addition of the `SendIBCPacket` utility function, which facilitates the sending of IBC packets over specific channels. This functionality was then integrated across multiple modules, namely `ccv/provider/keeper/relay.go` and `ccv/consumer/keeper/relay.go`, to facilitate inter-chain communication and validator set updates. Additionally, the user was involved in adding and configuring proto generation capabilities within the project.
