Bug fix file selection on Mac, process multiple series in microscopy files

In previous versions, a bug emerged in the file selection dialog from multi-task-manager, prohibiting selection fo files for analysis. This bug is fixed with version v0.0.6.

In addition, v0.0.6 is able to process open microscopy file formats with multiple series - all series in the file are then processed independently and the results are output. In previous versions, only the first series in the file was processed.
