Structured output format

[flying-sheep]

I want to get just the value, but the only options seem to be

• print using some undocumented human-readable format
• export using some unspecified default format
• export using DMPSTORE format

How about a format option for JSON? Or just the plain value?

+1 for dumping raw value of efi variables for consistency with -w option.
The man says that --datafile could be used to "load or save variable contents from ".
As a result missing way to dump raw content of the variable is confusing.
