New variant needed in the enum of commitment_proof

[livelybug]

Hello,

The CommitmentProof has 4 variants Exist, Nonexist, Batch, Compressed, none of them matches the structure of the corresponding proof in Substrate.

We use a temporary work-around compose_ibc_merkle_proof to insert the Substrate's proof into the CommitmentProof currently.

Is it possible to create a new variant in CommitmentProof for Substrate?

Thank you

I think it's possible. Changes to CommitmentProof would ideally go via this repo: https://github.com/confio/ics23/tree/master/rust upstream, then we'll update our dependency and the needed modifications will be available in ibc-rs also. Would you mind flagging the issue and motivation for the chance on ics23 repo?

Thanks, it's flagged in cosmos/ics23#80
