Title: Remove loss product from zonal statistics (only keep points count, loss sum and avg)

As also Chris agrees, it was useful to (recently) add the average loss for each zone, but contextually we also added the product of losses, which was actually pretty meaningless (a single point with zero losses would make the whole product zero). Therefore we are removing it.
