Support for nested JSON

[johndagostino]

hey @iximiuz - great project

I've been playing around with it with kubernetes logs which are json output and one feature which would be awesome would be nested json objects as part of the map

pq 'json | map { .msg, .time, .res.statusCode as statusCode, .req.url as url } | select url'

where log entry is

{"name":"project-name","process":0,"environment":"sandbox","hostname":"masked-magic-api-7679cdd899-wbznv","pid":1,"req_id":"704a1e50-e03b-11eb-bf79-51b92d981c1b","level":30,"res":{"statusCode":200},"duration":0.7862819999999999,"req":{"url":"/health","reqId":"704a1e50-e03b-11eb-bf79-51b92d981c1b","method":"GET","query":{},"userAgent":"curl/7.64.0"},"msg":"request finish","time":"2021-07-08T22:25:45.654Z","v":0}

Hi @johndagostino! Thanks for the feedback! Indeed, that would be a great addition to the current mapper's capabilities. I'll definitely add it once I'm back from vacation!
