feat(super-stream): enable customized consumerRef, offset

[haile-vnm]

⛔Before

client.declareSuperStreamConsumer(
      {
        superStream: superStreamName
        // consumerRef: "super-stream-[random-uuid]", as default, can not change
        // offset: Offset.first(), as default, can not change
      },
      (message: Message) => {
        // handle message logic
      })

✅After

client.declareSuperStreamConsumer(
      {
        superStream: superStreamName,
        consumerRef: "consumer-group-name", // defined by user
        offset: Offset.next() // defined by user
      },
      (message: Message) => {
        // handle message logic
      })

Hello, sorry for the delay. We were unsure at first about allowing any type of offset for super-streams, in particular numeric and last offsets since the result on the consumer side depends on the number of partitions. That said, after a bit of internal discussion we agree on this behavior.

One note: the CI pipeline fails when performing the format check on a test file. Could you run a npm run format and update the PR?

Hi @icappello ,

I fixed the format. Please help me to check it again. Thanks!
