Parses and converts data formatted in DSV array to a manageable internal format.

@param {Array.<Array>} arr - A 2D array containing of the DSV data.
@param {Object} options - Option to control the behaviour of the parsing.
@param {boolean} [options.firstRowHeader=true] - Whether the first row of the dsv data is header or not.
@return {Array} Returns an array of headers and column major data.
@example

// Sample input data:
const data = [
["a", "b", "c"],
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
];
