Add support lemesh.remote.ts4

[Marsmz]

I recently purchased a knob device, the model is https://home.miot-spec.com/spec/lemesh.remote.ts4. I found that the current version of gateway3 does not support this device. I tried to write a converter myself, and it seems that all the functions are working properly. I hope that support for this device can be added in future versions. Thank you.
