Aeotec doorbell 6 support

[Swaagie]

Added an Aeotec doorbell 6 but it doesn't support the type/properties yet? The adapter is able to detect it and it includes it

zwave-adapter:  10: ready    RoutingSlave     AV Controller       0x1  ZW162 Doorbell 6                         zwave-f220bac6-10-Doorbell 1 

I'd like to contribute the work needed to be done, but might need some pointers on where to start. I'd reckon https://github.com/mozilla-iot/zwave-adapter/blob/master/zwave-classifier.js is a good place to start. But do you have any tips on how to discover all available commands/property ids?
