WIP: Fix file handling

This MR fixes some bugs and brings several enhancements according to output file handling. A new output folder structure was implemented, creating a subdirectory in the output_data directory for each chip ID. Output files now have a run number instead of a timestamp in the file name. Scans now load the configuration of the previous scan by default. If there is no previous run in the output directory, a default configuration defined in /scans/configuration.yaml is used.
