Converts a comma-separated values (CSV) string to a 2D array.
- Use `Array.prototype.slice()` and `Array.prototype.indexOf('\n')` to remove the first row (title row) if `omitFirstRow` is `true`.
- Use `String.prototype.split('\n')` to create a string for each row, then `String.prototype.split(delimiter)` to separate the values in each row.
- Omit the second argument, `delimiter`, to use a default delimiter of `,`.
- Omit the second argument, `delimiter`, to use a default delimiter of `','`.
- Omit the third argument, `omitFirstRow`, to include the first row (title row) of the CSV string.
