Describe your issue

I have noticed four issues with the csv2json command.

command: csvtk csv2json testdata.csv -o testdata.json

input file testdata.csv:
test
none
"Make America ""great"" again"
\nations
"This is a
MULTILINE
string"

actual output file testdata.json:

[
  {
    "test": null
  },
  {
    "test": "Make America "great" again"
  },
  {
    "test": "\nations"
  },
  {
    "test": "This is a
MULTILINE
string"
  }
]

expected output file testdata.json:

[
  {
    "test": "none"
  },
  {
    "test": "Make America \"great\" again"
  },
  {
    "test": "\\nations"
  },
  {
    "test": "This is a\nMULTILINE\nstring"
  }
]

Comments:

• issue 1: I want "none" to be depicted literally and neither changed to "null" (no option) nor "" (empty string with option -b)

• issue 2: In JSON, double quotes have to be escaped with a backslash (\")

• issue 3: In JSON, backslashes have to be escaped with a backslash (\\)

• issue 4: In JSON, the line breaks of a CSV multiline cell have to be depicted as \n

Thank you

Thank you very much for the great csvtk tool!
