GEN3PLUS: Consideration of subsequently delivered data records

[s-allius]

The GEN3PLUS inverters sends after a connection setup or reestablishment, the missing data together with the realtime data. In the Power on Timegraph we will see glitches in that moment:

We want to handle this situation and send the non realtime data with a proper timestamp to home assistant, so that they will be inserted in the database at the proper place. Then we should see a permanent growing Power on Timegraph.
