Adding support for sensors Digoo DG-R8S with TFA (similar to Nexus) protocol

Also added ID and channel tags to MQTT message for simplify of message routing in NodeRed

Do you have any description of TFA protocol?

Greatly appreciated if support for digoo Dg-r8s will be added 👍

Unfortunately I have no DG-R8S sensor and cannot test the code with this device.

I want to help with that. I can send you ~5$ or a sensor if you're in the neighborhood.

Thanks for the support :-) I can prepare a version of the program that supports Digoo DG-R8S. If you agree to test it we can proceed this way.

Gladly! For the moment I have 2 sensors and can get 2 more.

@dpomparau have you tried testing this PR on the devices?

No, sorry, just Digoo DG-R8S and Digoo DG-R8H.

Oh sorry, I meant Digoo DG-R8S. Has it worked for you?

Yes, with this change it works. I saw some difference between R8s and R8h at humidity values but the program works without issues.

Great. Thanks. Trying it with the same devices as we speak.

Breaks compatibility with existing sensor. Will reuse it when support for multiple sensor types added.
