• Adding two state sensors for RFC1628 using the new format (based on the RFC it's a single OID, don't need to get multiple).
• Removed the two precedent informations that were not a sensor (Estimated minutes remaining & Minutes on Battery) because I don't know where to put this information, no category for these kind of graphs.

Details: #5977

Thanks for this @FTBZ .

One of the removed items is runtime so I've recreated that.
