DESCRIPTION
-----------
For the NVMe device given, sends an identify command for namespace list
and provides the result and returned structure.

The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
If the starting namespace in the list always begins with 0 unless the
`'--namespace-id'` option is given to override.

On success, the namespace array is printed for each index and nsid for
a valid nsid.
