Summary

When transferring images to the Live Viewer path, if the images are arriving slowly or are corrupt, then the Intensity in the Live Viewer is not displayed correctly, with errors around loading of files.

Steps To Reproduce

Open Live Viewer with the Intensity Plot activated.

Run the simulator with slow mode and tiff files

python scripts/simulate_live_data.py -s /data/imaging/tof/MCP_Fe_Calibration/Fe_Powder_Run1_PH60_Dis50mm_NewShutter/Corrected/ -d /tmp/live_test/ -r 1 --mode slow

(with the paths replaced with the locations on your system)

Current Behaviour

When the corrupt image is displayed, an error dialog pops up and the intensity plot does not display correctly

Expected Behaviour

The intensity plot should behave as expected, ignoring when partial or faulty images arrive.
