Feature Request: Extract and Display Battery Level from BLE Beacon iBeacon UUID

Hi, thank you for this excellent project—it works very well and is impressively precise.

I recently started using a keychain-type BLE beacon powered by a CR2032 battery. I believe it uses the DA14585 chip and supports advertising its battery level within the iBeacon UUID.


Specifically, the last two characters of the UUID represent the current battery level as a hexadecimal value (for example, "64" indicates 100%).

I'm wondering if there is already support for extracting and displaying this battery level information in Home Assistant. If not, I would be happy to help implement this feature or assist in any way needed.

Thank you again for your great work!
