Description
At the moment AFAICT (!) I can't get the index of the current line. I'd love something like:
.on('data', function(line, index) {... }
This is useful in a whole bunch of situations. Would it be possible to add - e.g. i'm implementing a head operator for a csv in https://github.com/okfn/datapipes

Research direction
Start by tracing the parser's .on('data', function(line, index) {...}) event interface and how data events are emitted. Check the datapipes head-operator use case, then verify that each emitted line includes its index and that existing streaming behavior remains intact.
