[Feature request]: Missing functionallity in KES-606US-L3

[dales]

Is your feature request related to a problem? Please describe

The Zemismart 2 Gang and 3 Gang light switches (as seen here) should behave the same and have the feature set. However the 2 Gang is identified as a Tuya device and the 3 gang as a Zemismart device

But they are the exact same device besides for the 3rd button

Describe the solution you'd like

I would like to see support for the same features the 2 gang has and is missing in the 3 gang

countdown, switch_type, inching_control_set

Describe alternatives you've considered
