Hi there,

Great set of utilities!

I was just wondering if there would be a problem with supporting 'streaming' json from the csv2json utility.

Similar to #275 , I would like to emit json without the surrounding array notation, so :

{foo:1}
{foo:2}
{foo:3}

This would mean that for a large csv file, there isn't the necessity to pull it all into memory first.

Ideally this would be done via an optional --stream option that defaults to false.

Happy to work on a PR if that sounds like something csvkit could/should do.

Implements json streaming for array output
f852dab 
This is to address issue wireservice#355 and to allow json to be 'streamed' - that
is, each object in the array be written out separated by a newline, rather
than output as one single array. Allowing this means we can convert
large csv streams to json without waiting until the end to see the
output. Many json-processing tools can deal with streaming json (for
instance jq).
