Support multi msg txs in the celestia-grpc-client wrapper #331
Description
Description
The celestia-grpc-client crate exposes a single function send_tx: https://github.com/celestiaorg/celestia-zkevm/blob/main/crates/celestia-grpc-client/src/client.rs#L94
We should either:
- Add a new method which supports accepting multiple msgs (of arbitrary length).
- Refactor the existing method to accept multiple msgs
This is a requirement for batching n MsgProcessMessage and a MsgSubmitMessages proof.
