Tendermint ConsensusState -> Any can crash if out of memory

[plafer]

Here.

This probably involves updating tendermint-rs's Protobuf in a similar way that was done for the Protobuf in ibc-proto-rs (which removed the Result return for encode_vec()).

I don't know, Why use

ibc-rs/crates/ibc/src/clients/ics07_tendermint/consensus_state.rs

Line 10 in cd3a266

use tendermint_proto::Protobuf;

this Protobuf, otherwise ibc_proto::protobuf::Protobuf.
https://github.com/cosmos/ibc-proto-rs/blob/9e87819bf686d2fd93d1e338943c9721fc0f3e50/src/protobuf/mod.rs#L74

I think this maybe help this.
