[mielecloud] Add support for Kochfeld mit Dunstabzug KMDA7676

[andysei]

Hi,
I use openHAB 4.2.3 and mielecloud. While everything works fine for my fridge and for the oven, my hob does not appear in the inbox.
So I added the hob as a thing with its serial number as Device identifier manually.

The hob thing is shown in state online and with modelId Kochfeld mit Dunstabzug KMDA7676. Property plateCount is displayed as 0.

With log set to debug and disabling/enabling the bridge I see this line:

[rnal.discovery.ThingDiscoveryService] - Unsupported Miele device type: Kochfeld mit Dunstabzug

...this is why I open this feature request.

Kind regards
Andreas

I just realized that plateCount is updated to 4 when I switch on the hob. It is reset to 0 once I switch the hob off. So maybe this is just a wrong logging message?
