"Shelly BLU H&T Display ZB" sends values 0,1 _and_2_ for "0x1E light"

[oli-h]

Describe the bug
According to BLE advertising in the BTHome v2 format, the sensor value "light" (Object ID 0x1E) is a "Binary Sensor data" and should only send values "0" (=false) or "1" (=true)

Though, Shelly-device "BLU H&T Display ZB" also sends value "2"

To Reproduce
Record the BLE advertising and light up a torch onto the illumination seonsor of the device.

Additional context
Looks like 0="dark", 1="low light" and 2="bright light".
I don't say it's a bad idea - but I say that the device does not follow the specification (or the specification should be adapted)

I have discussed this in the past with Shelly and explained that we can't modify the existing sensor since it may break other devices.
We agreed that Shelly will create a PR here to create a new sensor type
