Save Current Figure

sysplot.save_current_figure() saves the active Matplotlib figure to a file next to the calling script. It uses a structured naming convention Bild_{chapter}_{number}_{script}{_suffix}.{fmt} and creates the output directory {folder}/{language}/ automatically. The file format, output folder, and transparency all default to values in sysplot.SysplotConfig.
