2.2.0

• The return type for maxminddb.open_database() has been simplified
  to be just the Reader class as opposed to a union of that with
  the extension class. This is done by casting the extension to
  Reader. The extension class has the same public API as the
  pure Python implementation. This simplifies type checking for users of
  this library. The Reader class is exposed as maxminddb.Reader.
