Support for "Soft Air" on AC

[AndreiArdelean1]

Is your feature request related to a problem? Please describe.
I'd like to have support for "Soft Air" feature in the integration. With soft air, the ac blows the air through a different slit on the unit while the main louver is closed. Soft air can be either on or off and, it can have values from -4 to +4

Describe the solution you'd like
I'd like 2 new entities in home assistant for "soft air". One for turning it on or off, and one for setting the value

Describe alternatives you've considered
I haven't found many alternatives to that problem

Additional context
Here are the values from the device JSON that I've gathered:

Off -4: 'airState.tempState.discharge': 32772.0, | binary: 01000000000000100
On  -4: 'airState.tempState.discharge': 98308.0, | binary: 11000000000000100
On  -1: 'airState.tempState.discharge': 98305.0, | binary: 11000000000000001
