 - Re-export the `ics23.cosmos.v1` Protobuf definitions from the `ics23` crate instead of including them directly in this crate.
   The proto definitions are exported both under the `ibc_proto::cosmos::ics23::v1` module and under the `ibc_proto::ics23` module
   in an attempt to preserve backward source compatiblity.
