tape/helpers/snapshot_reader: sort chunks by inode (per index)

sort the chunks we want to backup to tape by inode, to gain some
speed on spinning disks. this is done per index, not globally.

costs a bit memory, but not too much, about 16 bytes per chunk which
would mean ~4MiB for a 1TiB index with 4MiB chunks.
