Add support for bitcode

[iheart2code]

When I try to include this in an iOS 9 project, I get errors about bitcode support not being available on a certain ARM architecture. As a result, I have to disable bitcode for my entire app.

This library vendors the release versions of libjpeg-turbo which so far do not ship with bitcode.

A workaround which works for me is to disable bitcode just for the Concorde Pod. It's still enabled for every other Pod and the Project.

And here's a build script for building libjpeg-turbo with bitcode enabled: https://macteo.it/build/2016/08/09/libjpeg-turbo-with-bitcode.html

So this issue is now solvable by the contributors?
