fixed usage for only one scenario year -> removed drop() when reading in files and adjusted subsequent apply() calls

fixed ecorisk_wrapper to work with timeseries again; added ecorisk_combine_hist_and_scen_data function; improved biocol_plot_ts function

now the full files_list will be checked, while you can also add other output names via replace_input_file_names

Merge reviewed package into main

See merge request !6

added function argument replace_input_file_names to handle different file names without the need to change the metric_files.yml file
