Add zhimi.airp.cpa4 support

[w-marco]

Hi, I got the new Air Purifier 4 Compact. zhimi.airp.cpa4

It is sadly missing support in this wonderful integration. The specs are here:

https://home.miot-spec.com/spec?type=urn%3Amiot-spec-v2%3Adevice%3Aair-purifier%3A0000A007%3Azhimi-cpa4%3A1

Would it be possible to add it? It works locally with a token from what I can see.

Hi, I have it too. Yes, it works locally with a token.

I do also have this Air purifier and it would be great to see the support for it. Thank you!

In HA community suggested to use other integration (I'm not sure I can reference other integration here)

Is support planned for this device? Is there any information needed? Any testing or similar?
