[enhancement]: Person-detection switch presented to HomeKit
### Describe the solution you'd like

Hi team,

It would be great if a switch could be presented to HomeKit for activation of person detection by a Eufy camera. 

This would enable us to create automation triggers based on human detection rather than simple motion detection. Much more reliable!

The Home Assistant equivalent of this plug-in can do this https://github.com/fuatakgun/eufy_security#features

Thoughts?
