v0.2.0

• Breaking changes:
  • AirQ constructor requires an aiohttp.ClientSession
    This session is to be used for all requests during the lifetime of the
    object.
  • .test_authentication() -> bool => .validate() -> None
    Instead of returning False the new method raises InvalidAuth
  • .drop_errors_from_data => .drop_uncertainties_from_data
    To avoid ambiguity
• Features:
  • AirQ provides fetch_device_info which returns a subclass of
    NamedTuple with some handy information (mainly for the purpose of
    subsequently passing it on to Home Assistant)
