CSV to List<Map<String, String>> instead of the normal List<List<String>> scheme of the original csv package

// Instead of this output:
[
  ["column 1", "column2", "column3"],
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9],
]

// you will get this output:
[
  {
    "column 1": 1,
    "column 2": 2,
    "column 3": 3,
  },
  {
    "column 1": 4,
    "column 2": 5,
    "column 3": 6,
  },
  {
    "column 1": 7,
    "column 2": 8,
    "column 3": 9,
  },
]
