Neato binding fork with Vorwerk support

Introducing Vorwerk support

A new vendor parameter has been introduced. Default value is Neato and should not affect the binding in any way. Other possible value is Vorwerk. Selecting this will redirect all requests to Vorwerk server instead of Neato server.

Note: due to certificate issues with Vorwerk server, another possibly disadvantageous server implementation with disabled certificate validation had to be used, which may cause issues.
