Describe the bug

When we upgraded from [email protected] to version >=6.1.0, our csv parsing logic broke.
We use from_line in our logic depending on the file.
We noticed that in [email protected], Parser.options.columns used to be set to something that looks like:

[
  { name: 'invoiceReference' },
  { name: 'sequenceNumber' },
  { name: 'providerNumber' },
  ...
]

Which works for any value that is set for from_line.

However in 6.1.0+, when you set from_line >= 2, Parser.options.columns becomes:

true

To Reproduce

I believe this also needs a CSV file with a BOM char.

Example:

        const csvIterator = Fs.createReadStream(localFilePath).pipe(
            CsvParser({
                columns: true,
                trim: true,
                bom: true,
                from_line: 2
            })
        );

        for await (let record of csvIterator) {
                console.log(csvIterator.options?.columns); // will log out 'true'
        }

Additional context

It looks like we can use another field Parser.api.options.columns. This is set correctly for all scenarios.
But hopefully this might help someone who had the same issue.
