Probably has to do with using `try/catch` whis is not omptimized by V8. Different parser is 10 times faster on my machine.

Edit: `fast-csv` seems to be using a lot of `RegExp`s on each iteration which can't be that fast compared to csv-parser which seems to simply go over each symbol (state machine?).

A lot better but that’s still 5× slower than Python.
