Add support for KMDA 7476 FR

[Adi146]

I'm trying to add my miele cooktop to home assistant using your custom component. When I start my Home Assistant I only see one entity named miele.miele_000176361536 and an error logged. It would be nice to have full support for this device too. The full product ID is KMDA 7476 FR

It seems like there aren't even docs for this device, so we will probably have to wait for this.
