Added support for auto_light:

when set auto_light: true in config unit will always turn light on when power on and turn light light off when power off. Light entity id should be set but is optional and can be used to control light for example in sleep mode
Added support for auto_xfan:

when set auto_xfan: true in config unit will always turn on xFan in cool and dry mode. There is no need to set xfan entity id, even if it is set, it will be ignored
Added support for target temperature entity id

when set target_temp: input_number... in config we can control target temperature with input_number helper.
Useful when someone wants to build a custom layout, for example with custom:button_card. Input number should be declared with attributes min: 16 max: 30
