default value for `-l` and `-s` options seems to be wrong

[VladimirAlexiev]

According to online help, the lint and safe options are turned off by default:

# jsonld canonize -h
Options:
  -l, --lint             show lint warnings [false]
  -s, --safe             enable safe mode [false]

I have a file with a couple of defects:

# cat input.jsonld
{
  "@context": {
    "@vocab": "http://schema.org/",
    "countries": "http://publication.europa.eu/resource/authority/country/"
  },
  "@graph": [
    {
      "@id": "countries:ITA"
    },
    {
      "@id": "http://people.example/Homer",
      "full_name": "Homer Simpson",
      "country": {
        "@id": "countries:ITA"
      }
    },
    {
      "@id": "http://people.example/Lisa",
      "full_name": "Lisa Simpson",
      "country": {
        "@id": "countries:ITA"
      }
    }
  ]
}

If I feed it to canonize, it complains about both "safe" and "lint", there's no way to disable those checks, and it produces no output:

# jsonld canonize input.jsonld

The other modes (expand, flatten, format) don't issues such errors/warnings
