---------                     -------
601034920                     156 files

```

Furthermore allow `inspect` to do direct decode from `mc`, for example:

```
λ mc admin inspect --json local2/testbucket/nyc-taxi-data-10M.csv.zst/*|inspect -json
Output decrypted to inspect.5f0643b2.zip
```

- Correct error, forward non-EOF errors.
- Add some extra safety. Log FNF when no files.
- Add `xl-meta` zip support.
For `xl-meta` multiple inputs output object with names as key.
Automatically switches `xl-meta` to single-line output when multiple objects.
Add double-star wildcard support to xl-meta input.
