Support for the NUON format.

The NUON format is a superset of JSON designed to fit the feel of Nushell. Some of its extra features are

  • trailing commas are allowed
  • commas are optional in lists
  • quotes are not required around keys or any bare string that do not contain spaces or special characters
  • comments are allowed, though not preserved when using from_nuon

Example

below is some data in the JSON format

{
    "name": "Some One",
    "birth": "1970-01-01",
    "stats": [
      2544729499973429198,
      687051042647753531,
      6702443901704799912
    ]
}

and an equivalent piece of data written in NUON

{
    name: "Some One",       # the name of the person
    birth: "1970-01-01",    # their date of birth
    stats: [                # some dummy "stats" about them
      2544729499973429198,
      687051042647753531,
      6702443901704799912, # note the trailing comma here...
    ], # and here
} # wait, are these comments in a JSON-like document?!?!
