NanoPi Duo pin mappings added

[sgjava]

Feature we discussed in #16

[rm-hull]

The QA build failed - see https://travis-ci.org/rm-hull/OPi.GPIO/jobs/323631901#L563

You should pip install flake8 locally and fix the warnings that flake8 is complaining about.

[sgjava]

Added space CI complained about.

Looks like the failure in the test is not caused by the code I added. Can you please verify?

[rm-hull]

No, not caused by your changes. There are a couple of intermittent failures ... See #19

[rm-hull]

👍 All good, just a few tiny observations.
Also, add your name & github handle to CONTRIBUTING.rst as well

No need to include created date & author - this can be obtained from git log, but worthwhile setting docstring header to something like:

Alternative pin mappings for NanoPi DUO board (see http://...)

[rm-hull]

Use the RST code formatting extensions, so this would become:

Usage:

.. code:: python
   import nanopi.duo

   GPIO.setmode(nanopi.duo.BOARD)

[sgjava]

OK, bringing this up to standards :)

[rm-hull]

👍 - good stuff, will roll out 0.3.1 shortly with this in

[sgjava]

Cool, it will be nice not to use my fork :)
