Provide flag for outputting only raw data, not meta data

[phillijw]

The lines like this:

➜ [my.topic.name] [05 Nov 21 09:23 CDT] [Published Msg]

are getting in the way of parsing data that comes out. For instance, I want to use jq utility to parse the JSON messages I have but I first have to filter out the lines mentioned above. I do this with grep -v "➜" but it's a bit of a hack. A flag to turn this off would be great.

(Thanks for this great tool!)
