dataset csv-schema has a double negative command option

I understand the logic behind this, since we should anticipate that the first row is a header, and it seems like we would only say something if the first row is not a header. However, this results in the logical construction "Yes, we have no headers," a Sartrian construction ("Bring me a coffee with no cream." "We are out of cream, would you like it without milk, instead?"

I would prefer a switch such as --firstRowHeader, with a default of true.

--no-header
Don't use first line as CSV header (default: false)
