What did I do here?

I modularized the time series sources a bit further:

• Having a distinct mapping source, that provides information on which time series is there for which model as well as the types of time series aka. meta information
• The time series source itself only provides information about one time series at a time (including the possibility to query results for periods in time or specific instances in time)
• The CsvTimeSeriesSource` has a factory to build correct source from given meta information

Thank you very much for your contribution. 👍🏼
Coverage is also fine for now, as mainly equals or exceptions are not tested.
Just had a few minor remarks that should be fast addressable. :-)
