Add support Sonoff SNZB-03P

[Marcelo-Y]

First of all thank you very much for your great job on this.

I'd like to have SNZB-03P attributes as entities, like you have done with SNZB-06P in the "master" so far.
I started using SNZB-03P and found it much better to use entities like in SNZB-06P than as attributes.
Here are the files:
snzb-03p debug.txt
snzb-03p diagnostics.json

Hope it can be possible.
Thank you very much.
