want `jq` or `json`

It's quite useful to have a tool available everywhere that can format JSON input, select parts of it, and transform it. I'm partial to json but I gather jq is much more prevalent these days and would avoid having to ship Node.

This is also #85 which seems to have more discussion. I'm closing this copy of the issue in lieu of the newer one.
