Add refreshResults & Paginator

[bh2smith]

We rename a previously internal method _runInner to refreshResults which executes and loops until execution is complete (but does not fetch results). Additionally, we Introduce a new class Paginator which fetches and caches and index result sets by page. This class exposes an api similar to the Dune interface result page navigation:

• nextPage, previousPage, lastPage and pageN.

Paginator can be constructed from the return value of refreshResults and a client of type ExecutionAPI.

Will want to add docs on how to use this, but the test introduced should give a pretty good idea of how to test it out in a front end.

Note that

1. the first commit (00ac359) is unrelated (fixing e2e test based on Dune's internal data format changes and expired query results).

2. the second commit (774b789) is just renaming an existing function and making it public (in preparation for public use)

3. 🔑 the third commit (69c3088) This is the most relevant and substantial change introduced here: Paginator 📃

@bh2smith Moving our chat here
Checked in with a few folks who use Dune API, and some front end devs, seems like more folks prefer the current way in SDK which is to separate out execution from Paginator :)

Sounds great @agaperste, so shall we merge and publish this as is?
