Add loader support for typeform data

The premise is that the loader could be given an export of typeform data, and convert that into Polis-like vote data

Example typeform: https://form.typeform.com/to/DGgVMUH5

Two conversion formats are possible (liberal vs conservative) where D = disagree (-1), P = pass (0), A = agree (+1)

liberal: 1/2/3/4/5 => D/D/P/A/A
conservative: 1/2/3/4/5 => D/P/P/P/A

It would be important for (as much as possible), everyone to have the same understanding of what 1/2/3/4/5 mean. Perhaps it's better to just use a different question format, and only offer disagree/pass/agree as options.

Proposed Typeform form recommendations:

• a recommended labeling of scale: complete agree / pass / completely agree (?)
  • to allow consistent baseline
• statements are required (can't be skipped)
• can't submit partial

obvious there's no comment routing here -- the order of statements is whatever moderator chose. but it's still maybe an interesting way to get data into a polis-like pipeline. Since there's no equivalent to comment routing, it would be important for only full response sets to be included (no partial responses).
