TimeSeriesSource: get activation ticks #543
Description
As discussed in ie3-institute/simona#98 (comment), the interface and corresponding implementations of edu.ie3.datamodel.io.source.TimeSeriesSource should be enhanced with a method that returns all activation ticks for a time series (after a given time):
List<ZonedDateTime> getTimeKeysAfter(ZonedDateTime time);
This way, the implementations can take into account efficient methods for each data source type (e.g. with SQL this can be solved with a simple and quick query).
