1028 Reduce export_input_data_county_timeseries

[HenrZu]

Changes and Information

Please briefly list the changes (main added features, changed items, or corrected bugs) made:

• The current code for the function export_input_data_county_timeseries is similar to the functionality in read_input_data_county.
• This redundancy also increases the susceptibility to errors, as both codes always have to be maintained.
• More unit tests for the extrapolation process

If need be, add additional information and what the reviewer should look out for in particular:

I have compared the runtime of the new extrapolation function with the old one. The results are almost identical. The result shown are for the secir model.
