export_input_data_county_timeseries is too similar to read_input_data_county

[HenrZu]

Bug description

The current code for the function export_input_data_county_timeseries is similar to the functionality in read_input_data_county but are completely independent from each other. This redundancy also increases the susceptibility to errors, as both codes always have to be adapted. It would be better when they would share the same functionalities since they work nearly equal.
