feat: add t0123 ipns

• build the test
• add a system to run 2 queries and compare the outputs

I'm cool with proceeding with this as-is until we get more use cases for multi-request/multi-response setups.

Some ideas/thoughts I got looking at it:

• Should a test struct have both Request and Requests prop on it? Could we get away with having one?
• Do we want to limit duplication if parts of multiple requests are the same? As in, should we allow, for example, Query method on the RequestBuilder list and have it set query for all the requests?
• Similarly for the expects, would it be useful if we were able to do all the checks that we have on ExpectBuilder also on ExpectsBuidlers?
• This one's a bit unrelated but would it make sense for SugarTest to be a builder as well?

Just wanted to dump ^ before I forget but no need to dig into it now.
