Position Entity for showing vaccuum robot/other models in real time

[peteh]

Is your feature request related to a problem? Please describe.
It's somewhat possible to get the coordinates of xiaomi/roborock vacuums (https://github.com/PiotrMachowski/Home-Assistant-custom-components-Xiaomi-Cloud-Map-Extractor).
I'd like to use those to visualize a 3d model of the vacuum in the 3d model of the flat.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Not sure what's the best way, but for example like this:

• configure vacuum entity - either by sensor entities for x,y,z or by vacuum entity itself (latter one would be more generic for other systems as well, e.g. person tracking)
• add transformation for coordinates from robo coordinate system to flat coordinate system
• take the robot model group object_id
• When the position of the sensors update, the position of the model also is moved accordingly

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Seems like there are not really other solutions at the moment

Additional context
Add any other context or screenshots about the feature request here.

Use Cases:

• Visualize moving persons, e.g. with data from camera/beacon tracking
• Visualize vacuum robots based on their position in their own map
