Options for `stream.Transform` is not transferred from `Stringifier`

[redexp]

Hello, I found a bug in Stringifier class when it passes options to stream.Transform.

node-csv-stringify/lib/index.js

Lines 98 to 100 in 49f1dc3

	super({...{
	writableObjectMode: true
	}, ...options});

On first look it seems that super will get merged options from Stringifier but on that line options is undefined all the time. Maybe instead of options there should be opts? If not then basically code should be rewritten to super({writableObjectMode: true}).

Thank you for reporting, passing opts was the expected behavior
