Should it also lead to an exception in case timeBasedValues is empty, since one could assume we would expect weather data when asking for it and those aren't there? Not sure about this, I might have to rethink on this.

Also, testing this would also be great.

I tested throwing an exception when timeBasedValues is empty, but that broke existing behavior and tests. For now we keep it simple: invalid coordinates throw a NoDataException, but valid coordinates with no data just return an empty series. Or do we really want it that strict? If so we could use my last commit which I reverted again.

It'd be great to have equivalent behavior across types of data sources, at least where it's possible

While looking through this, it came to my mind that some of these errors we could try and heal instead, before throwing an exception.

I realize this requires a bit more effort, but maybe it still makes sense to handle it in this PR? On the other hand, SIMONA has to deal with these new types of exceptions anyway, and at a later step it would crash less because we healed the problem instead.

Logging an error is obsolete when we also throw and exception in the next line, imho

Hmm. I think there's a way to heal this instead of breaking right away.
I'd say, if for a coordinate we cannot retrieve weather data, we try to provide the last available data (the available data for the last point in time before now) first. In this case, we also log a warning.
If that also fails though, we should throw an exception.
