Does not work with wolframalpha 3.0

[dgw]

Upgrading wolframalpha package to 3.0 broke this module on my instance (Py2.7).

[01:32:15] <~dgw> ;wa dgw
[01:32:23] <&Kaede> TypeError: object of type 'itertools.imap' has no len()
                    (file "/usr/local/lib/python2.7/dist-packages/sopel_modules/wolfram
                    /wolfram.py", line 52, in wa_query)

Prior to this update it was working fine. Reinstalling wolframalpha 2.4 and restarting the bot fixed it.

There will be two steps to fixing this issue, and a third step for the future once enough time has passed:

• [x] Update requirements.txt to request wolframalpha>=2.0,<3.0 (done in #6)
• [x] Rewrite code to handle both 2.0 and 3.0; require wolframalpha>=2.0,<4.0 (done shortly — 12/21) (done; "shortly" is relative, see discussion in #11 — May 10, 2017)
• [ ] [Future] Drop support for 2.0 and require wolframalpha>=3.0,<4.0 Not needed; both versions can be supported in parallel with minimal code smell

The most pressing issue right now is preventing users from upgrading to wolframalpha 3.0, so a new release with the first requirements update will be pushed soon was pushed shortly after posting of this issue.

Everything planned for this is now done. Closing.
