Add calibration import for CSV files and similar TXT files. The app will now extract and import the linear calibration out of your CSV file and enable it, if the CSV file has at least two columns. The first column will be used as the calibration source, because this is the most common way to do so. This is handy if your CSV files exports energy-calibrated bins instead of just raw bin numbers on top of the usual pulse height histogram data.
