structured exceptions (hard crashes, segmentation faults...), converts them to Slic3r::HardCrash exceptions and displays the exception using the usual PrusaSlicer way. The SEH handler is installed on the main background slicing thread as of now, therefore hard crashes in TBB worker threads are not handled.
