Add Reolink smart ai number entities

Breaking change

Proposed change

Add Reolink smart ai number entities for:

• crossline sensitivity
• intrusion sensitivity/delay
• lingering sensitivity/delay
• item forgotten sensitivity/delay
• item taken sensitivity/delay

For each of these smart ai types, the user can create up to 3 zones/lines in the reolink app.
In total you could therefore get 27 number entities from this.
However the user will need to first create the zones/lines, by default no zones/lines are set on a camera.
As soon as the user makes a new zone/line, those entities will be added to HomeAssistant (user does not need to reload, this is done automatically).

See https://www.reddit.com/r/reolinkcam/comments/1fbubli/ifa_2024_smart_ai_detection/
It is currently available on a handfull of specific models, but it will roll out to more models through firmware updates.
I know it is already available on the RLC-840A (latest firmware, you can update through HA).
I tested with a CX810 with beta firmware (not publicly available yet).
