Version 3.0.0

Breaking changes:

• device.createQodSession() now requires duration as a mandatory parameter
• device.getCongestion() now returns a list of Congestion objects

Changes:

• device.verifyLocation() may now return a "PARTIAL" result if the device is
  partially inside the verification area

Fixes:

• Previously due to a miscommunication device.sessions() would return all
  created sessions. These have now been correctly limited to device-specific ones
