Support multimessage transactions

[fedekunze]

Is your feature request related to a problem? Please describe.

Some transactions have multiple msg values, which we do not support yet as we're relying only on the first message. For eg:

  "height": "193168",
  "txhash": "7E129DFC4EC8887E50136E51252EA50F95FE3ECCEE1F56F722914975913E9106",

          }
        ],

      },
      "signatures": [

      ],

  }
}

Describe the solution you'd like

Support multiple message transactions on Voyager

Describe alternatives you've considered

a. Display both messages on the transaction (separated by a divider), or
b. Display multiple transactions with the same tx height and metadata (Li transactions)

Additional context

Mintscan explorer uses the a. approach:

Are multi messages even used by the SDK as of right now?

[faboweb]

I like the idea of just using the LiTransaction and wrapping them in a container. 👍

[fedekunze]

yes, I've seen lots of those txs on the explorers recently

gaiacli tx distr withdraw-all-rewards tends to be multi msg (one msg per validator you're delegated to), eg. https://stargazer.certus.one/transactions/122219:4554CDD3DDFD1DF897DB654EB0616A6BCEC6FBA52200F63291D516E5AE412FD8

Also certain power users (cough cough) are manually constructing multi-msg txs: https://stargazer.certus.one/accounts/cosmos1unc788q8md2jymsns24eyhua58palg5kc7cstv

Thanks @ebuchman ! I opened a PR to display them as "separate txs" until the final designs form @jbibla are done
