[Feature Request] - Lock Sensor: Change entity Picture based on its state

[ChristophCaina]

I really like the fact, that the sensor for the lock-state sensor is showing a picture, that matches the graphic from SurePet.

It would be GREAT, if the sensor could dynamically change the picture based on the state: unlocked / locked_in / locked_out / locked_both

locked_in:

locked_out:

locked_both:

Only for unlocked another / custom picture would be required.

Unfortunately, I haven't seen, where exactly the picture should come from
it seems, that this somehow comes from the attribute entity_picture - which I could not find

self._attr_entity_picture = self._surepy_entity.icon

it seems, that the icon image does change, but it takes increadible long until the picture will be replaced ...
