Create Adafruit_QuadAlphanum.py

[fschioler]

Hi.

I missed code in the Raspberry Pi library for handling quad alphanumeric displays.
An implementation based on the LEDBackpack is attached.

Best regards

@fschioler Thanks for this code! Wondering why Adafruit isn't merging the many, many PRs ..

we're in the process of splitting this library into multiple, manageable repositories that will be PEP8, py2/3 compat, and in pypi
it is a ton of work, no ETA for finishing...py3 compatibility in particular is hairy but we want to get that working before adding more code

@ladyada Thanks for replying - sounds good! pep8, py3 .. yay. FWIW, I've got my stuff working https://twitter.com/oberstet/status/706167559981305856 using above PR .. real-time display of votes from the Web. The display is nice and easy to use. Thanks for that too!

This library has been deprecated in favor of our python3 Blinka library. We have replaced all of the libraries that use this repo with CircuitPython libraries that are Python3 compatible, and support a wide variety of single board/linux computers!

CircuitPython has support for almost 200 different drivers, and a as well as FT232H support for Mac/Win/Linux!
