Improvements and fixes

The on-site analysis now keeps the result of every string, even on a large plant.

• After an on-site analysis on a large plant, every string keeps its result, where a few hundred of them previously went missing.
• Changes to a plant's components take effect in the on-site analysis started right after, instead of up to an hour later.
• Becker PV-Control data loggers can now be read by mapping the values they send.
