Short: `List directories and objects in the path in JSON format.`,
Long: `List directories and objects in the path in JSON format.
The output is an array of Items, where each Item looks like this

If --hash is not specified the Hashes property won't be emitted.
If --no-modtime is specified then ModTime will be blank.
If --encrypted is not specified the Encrypted won't be emitted.
The Path field will only show folders below the remote path being listed.
If "remote:path" contains the file "subfolder/file.txt", the Path for "file.txt"
will be "subfolder/file.txt", not "remote:path/subfolder/file.txt".
When used without --recursive the Path will always be the same as Name.
The time is in RFC3339 format with nanosecond precision.
The whole output can be processed as a JSON blob, or alternatively it
can be processed line by line as each item is written one to a line.
