Support for Goodway In wall relay

[tszalajITDev]

I created a configuration file for Goodway In wall switch using documentation provided on webpage: https://products.z-wavealliance.org/products/2948. I've tested it with the device on Domoticz. Configuration works and device reports it's outputs state changes.
