Similar to the overlay for the spatial anchor showing the loaded chunks, we can use the same rendering to also highlight any block, which will not be transfered during a spatial transport.

This should cover always blacklisted blocks like bedrock, as well as what is dynamically blacklisted. E.g. through the respective block tag.

This would be incredibly useful. Perhaps even an option in the spatial io block for it to only work when all the blocks inside will be transported?
