Description
Issue
When packing all external data into .blend file, all the preview thumbnails will get packed as well.
I noticed, when I used one BlendLuxCore-saved file on another computer, it then complained about missing images, when toggling "Automatically pack into .blend" off and on.
Besides all the thumbnails, this is isn't pretty either:

OS:
Blender version: 2.83
LuxCore version: BlendLuxCore-latest-win64

Research direction
Start by reproducing the packing behavior in Blender 2.83 with BlendLuxCore-latest-win64, using the reported Automatically pack into .blend toggle and a file with external data. Inspect the BlendLuxCore packing path and confirm that preview thumbnails are excluded; done means the packed file is not bloated by thumbnails and can be toggled on another computer without missing images.
