When counting blocks to generate block size histograms (`-bb`), accept a `--bin=` argument to force placing blocks into all three bins based on *this* size. E.g. with `--bin=lsize`, a block with lsize=512K, psize=128K, asize=256K will be placed into the "512K" bin in all three output columns. This way, by looking at the "512K" row the user will be able to determine how well was ZFS able to compress blocks of this logical size. Conversely, with `--bin=psize`, by looking at the "128K" row the user will be able to determine how much overhead was incurred for storage of blocks of this physical size.
