Get survey respondent paths

How respondents moved through the survey, for the Results flow chart. Query from, to (YYYY-MM-DD) and version. Returns { responses, other, sampled, paths: [{ path, status, nps?, count }] }: identical paths grouped (biggest 300), path = block ids in order (a completed one may end with its ending id, an open one ends where it stopped), nps = detractor | passive | promoter on the first NPS question. Reads the newest 20,000 responses (sampled: true beyond that).
