Fan/Mode support for heaters
<!-- PLEASE READ BEFORE REQUESTING A NEW DEVICE

* **Please explain your feature request in a one or two sentences.**
So my Smart Space Heater Max, which had support added in the latest beta, **has no "Fan" mode**. Fan mode can be manually activated by going to the fan accessory, which is grouped within the main accessory, and selecting 25%. This can be confusing though, as the heater, when in fan mode, shows in the Home app as heating. **Can a "Fan" mode be added to the main toggles, which are "Auto" "Heat", and "Off"?**


* **Is your feature request related to a problem? Please describe.**
It's not a huge issue, but really annoying. 


* **Any particular Govee devices that this relates to?**
H7134


* **Anything else?**
Just for clarification, my heater is unreleased. It has 5 modes- **Low, Medium, High, Auto, and Fan**. If those modes could possibly be added, that would be great! I don't know if the Home app allows that though. Attached are some supporting screenshots. Thank you!!
