jsonlines support

[eichin]

http://jsonlines.org/ is mostly a description of something people do anyway, namely "print json.dumps() is easier to parse than print" - it would be useful to have jsonpipe support this.

The trivial and useful (but horrible) shell workaround is

$ cat foo.jsonlines | while read -r J; do echo -n $J | jsonpipe; done

I'm suggesting either a -l option to explicitly say "restart the parser" or some implicit "the parser completed, start it with fresh state" mechanism.
