Check: additionalData can be null

https://github.com/52North/helgoland-toolbox/blob/develop/projects/helgoland/d3/src/lib/extended-data-d3-timeseries-graph/extended-data-d3-timeseries-graph.component.ts : Line 99

I note that this issue was brought up long ago and has not been resolved. I want to work on this issue.
Since there doesn't seem to be much activity at this repository, i'd like to know if it's still active. Is there another repository where all operations are carried out?

If additionalData can be null at line 99, you should guard against this possibility to avoid errors. You can add a null check before iterating over this.additionalData.
