0.3.1

This release transitions from the Human Interface Device API for accessing USB devices to the PyUSB module. Neither HDIAPI or PyUSB are developed actively, however PyUSB has released with a year of this writing and ships a viable module for Linux and macOS. I've submitted a PR to the HIDAPI python project to enable it's use on macOS, however I don't have much hope of having the PR accepted (or even looked at).
