Separate Artisanlib

[shyamd]

I'm actually wondering if there is any interest in refactoring out a lot of the core functionality into an artisan-lib that enables programmatic use of the device interface and associated tools. For instance, I've used the ailio interface to build some custom automation for my own purposes and others might appreciate having such an interface to any of the devices in artisan. Similarly, someone might have a use for some of the algorithms from the roast analyzer, etc.
