rpc response decode failed with recent released version of tendermint

[yihuang]

Does it only works with tendermint git version?
I used the most recent released version(0.33.6), I got many null decoding issues, also the gasUsed -> gas_used/gasWanted -> gas_wanted naming differences.

An example block_results response:

{
  "begin_block_events":null,
  "consensus_param_updates":null,
  "end_block_events":[
    {
      "attributes":[
        {

          "value":"AAAAAAAAAAAAAAAAAgAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAgAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=="
        }
      ],
      "type":"block_filter"
    }
  ],
  "height":"4",
  "txs_results":[
    {
      "code":0,
      "codespace":"",
      "data":null,
      "events":[
        {
          "attributes":[
            {
              "key":"ZmVl",
              "value":"MC4wMDAwMDMwOA=="
            },
            {

            }
          ],
          "type":"valid_txs"
        },
        {
          "attributes":[
            {

            },
            {

              "value":"d2l0aGRyYXc="
            },
            {

              "value":"W3sia2V5IjoiVW5ib25kZWQiLCJ2YWx1ZSI6Ii01MDAwMDAwMDAwMDAwMDAwMDAifV0="
            }
          ],
          "type":"staking_change"
        }
      ],
      "gasUsed":"0",
      "gasWanted":"0",
      "info":"",
      "log":""
    }
  ],
  "validator_updates":null
}

Compare to the one in unit test: https://github.com/informalsystems/tendermint-rs/blob/master/rpc/tests/support/block_results.json

We should update our CI image to the latest 0.33 release to guarantee we aren't missing any changes there. Currently, we are using 0.33.5:
