Created Unassigned: SBFspot doesn't create spot file for Sunny Multigate [171]

SBFspot 3.2.0 doesn't create spot file for Sunny Multigate.
line 531 in SBFspot.cpp
```
if (Inverters[0]->DevClass == SolarInverter)
```
Multigate is a CommunicationProduct Device.

I changed it to
```
if (Inverters[0]->DevClass == SolarInverter || Inverters[0]->DevClass == CommunicationProduct )
```
and now is working fine. I'm not sure if this change is safe for others. I have only Multigate so at least for me it is fine
