Provide more attributes from devices.

[oleh-shulha]

Hi all!

Guys, firstly i would like to express my deepest gratitude for the great integration! Thank you very much, you awesome!
Now closer to the point and my idea. I have several devices that provide attributes that do not exist in HA entity.

Ex. wifi heater

And this is devise state from tuya API:

As you can see, from API i receive 'work_state' property, which represent current heater state: 'heat' if it works and heat air, and 'warm' if the air temperature has reached the set and heater idle.

Or another example:
Tuya WiFi smart plug contains power meter, but not exists in HA entity state attributes:

So, in order to improve automation scripts, it would be great to provide this data so that sensors or other entities can be targeted at them.
In test purpose, i try to extend base.py TuyaEntity by those code:

@property
    def extra_state_attributes(self):
        state_attributes = {}
        for attribute, value in self.device.status.items():
            state_attributes[attribute] = value

        return state_attributes

And now, my entities expose all required data to HA:

Actually the question, do you think it would be useful in official Tuya integration? Of course, well-formed and tested code, not what I showed in the block above.
I would like to have this in the master branch so that I don't support it separately in my fork.
I would be glad to hear your opinion, thank you!

I would love this too, I have a motion and luminance sensor but HA only shows the Motion attribute
