ValueError: min() arg is an empty sequence #59

I've sliced over 4000 stl models with this tool, and all of them have been sliced successfully except for 5 models that failed to slice, and I've confirmed that the 5 models themselves are fine. These 5 models report the following errors：

`multiprocessing.pool.RemoteTraceback: """ Traceback (most recent call last): File "/home/ubuntuuser/anaconda3/lib/python3.10/multiprocessing/pool.py", line 125, in worker result = (True, func(*args, **kwds)) File "/home/ubuntuuser/anaconda3/lib/python3.10/site-packages/stltovoxel/slice.py", line 54, in paint_z_plane perimeter.lines_to_voxels(lines, pixels) File "/home/ubuntuuser/anaconda3/lib/python3.10/site-packages/stltovoxel/perimeter.py", line 10, in lines_to_voxels paint_y_axis(lines, pixels, x) File "/home/ubuntuuser/anaconda3/lib/python3.10/site-packages/stltovoxel/perimeter.py", line 40, in paint_y_axis min_idx = -min((x, -i) for i, x in enumerate(distances))[1] ValueError: min() arg is an empty sequence """

The above exception was the direct cause of the following exception:

Hi @wsyzy can you try this again with the new version of the code? I encountered a similar error while writing #62 and think that it may now be fixed. Thanks, Christian
