Long term statistics for inverter sensors

[mcflexus]

I see the ecu sensors have long term statistics enabled but the inverter sensors don't. Can you enable them? I think especially for temperature sensor it makes much sense to do so. Thank you for this great integration!

They are long term (at least when I quick tested it) Or do you mean something else?

[mcflexus]

I mean something else, this is just the history of a few days, long term statistics are stored for ever. See https://data.home-assistant.io/docs/statistics/

I see what you mean, state_class is missing. Are you able to add that to the integration?

[mcflexus]

Don't think that should be a problem. I'll try to find some time this weekend.

just made a pull request, tested locally and working as expected. #165

No problem!
