Add support for Mi Smart Microwave Oven
Hello,

Would it be possible to add support for the Mi Smart Microwave Oven?

**Model:** `chunmi.microwave.n20l01`
**SKU:** `MWBLXE1ACM`
**Link:** https://www.mi.com/buy/detail?product_id=10330

When setup in the plugin, it seems to connect successfully and is seen as a switch, but there are no additional controls. Toggling the switch also does nothing, and it does not reflect the current state of the microwave.

I understand this isn't the usual type of device controlled by HomeKit, so I don't expect support for every feature, but being able to at least start or stop it would be nice.

If there is anything I can provide (logs, testing, etc.), I would be happy to help the best I can.
