With the recent new network for Stockfish it appears that we need to do some more costly filtering on the datasets (official-stockfish/Stockfish#4295). Removing positions from the dataset degrades compression, so in some cases it might be better to mark positions with a special flag and skip them on load. I think it's reasonable to use score==VALUE_NONE as such a flag and this PR implements it.

I think this is useful.. don't know if this will help linrock with the current dataset, as he would have to recompute this from scratch, to add the positions... I assume.

Yes, the dataset would have to be redone.
