Add listeners for roborock

[Lash-L]

Breaking change

Proposed change

So the cloud api has a mqtt topic that we are able to subscribe to - and with that for some pieces of information, we can get an automatic update, i.e. you have an error or you start a clean or you change the fan speed.

Without the cloud api, the listeners wont do anything, but the code will still update at its normal frequency.

So we (preferably) use the local api to update on our fixed scan interval, and then we use the mqtt cloud thread to update when some things change.

Marking as draft until I figure out what I want to do for pytest

My test is interesting to say the least - and I know it probably isn't ideal, but i'm not sure a better approach. I am open to suggestions.

I have a question below about the test approach, given its patching an internal method.
