Word detection can produce words which have a small overlap. This is because the detection model predicts boxes which are slightly shrunk from their true size, and post-processing then pads the boxes to recover the "true" size.
This means it is possible for the average inter-word spacing in a line to be negative. When this happens a panic occurred when converting the spacing from signed to unsigned.
The fix is just to clamp the computed average spacing to be >= 0.
