Add support for WiFi bulb H600A


* **Is your feature request related to a problem? Please describe.**
I purchased a [Govee Smart Light Bulbs 1200 Lumen in Amazon](https://www.amazon.com/dp/B0CS6RDYYZ?ref=ppx_yo2ov_dt_b_product_details&th=10), and the model they ship is NOT the normal H6009, but a newer H600A. On Homebridge the plugin says the device is not supported, and that I need to create an issue with the following info:
