Add Imaxfire AWA2 water vapor fireplace (#5123)

* feat(devices): add Imaxfire AWA2 fireplace

* Update brightness mapping to use range instead of values

Replaced explicit mapping for brightness with a range definition.
- tests show that contrary to the comment, this works correctly, so if there is a bug that should be dealt with separately.
