Flow rate for heat pump

[donaldstod]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
I already saw the integration shows more values than I get from the LG ThinQ app.
Is there maybe a value representing the flow rate of the heat pump?
Solution additional entity showing the flow rate, if available.

Describe alternatives you've considered
No, alternative.

Additional context
If you need an LG account that has a heat pump installed I can support you :-)
Thank you!
