Enhancement: Support printing snapshot size in `snapshots` command
The `snapshots` command now supports printing the snapshot size for snapshots
created using this or a future restic version. For this, the `backup` command
now stores the backup summary statistics in the snapshot.
The text output of the `snapshots` command only shows the snapshot size. The
other statistics are only included in the JSON output. To inspect these
statistics use `restic snapshots --json` or `restic cat snapshot <snapshotID>`.
