WIP Attempt to track HS2WD-E siren status. help needed

[ghoz]

The HS2WD-E siren does not report back its state.
As the siren command has a duration (and a max duration config) , it will stop at some point, but the triggering system as no way to know that.
Attempts to track current state by looking at the mode, duration (and strobe) when the command is sent.

This is not ready to merge.

2 open questions :

• How to publish a state from a toZigbee convertSet context with a delay ? there is no easy publish available as in fromZigbee convert
• Where to properly implement all this without duplicating tz.warning ? would adding a flag to meta be the right place to turn on this virtual state ?

240 is a placeholder for the actual max duration for now

That's fine

What is the use case for this? Do you want to publish siren OFF after a certain time?

Yes, exactly . Not sure how other warning devices return their state, through ias Zone Status maybe, but this one doesn't return anything, which make it's use as an HA siren a bit tricky

I wanted to copy the idea of the occupancy sensors that don't reset their state, but as those timers are created from within fromZigbee convertSet they have access to publish, which is not available here...

We have to add a publish to https://github.com/Koenkk/zigbee2mqtt/blob/1accb8b66b95b99658c50e4c0209edcb946a5fe2/lib/extension/publish.ts#L230 in that case. Would you mind making a PR for that?
