JSON decoding less strict

[td5r]

I want the JSON decoding to map it received data to provided output port type.

Currently this fail because the JSON decoding checks for absolute equal JSON structure and don't allows sub sets or picking

@td5r I would actually move to use this https://github.com/thedevsaddam/gojsonq instead.
And implement it as an operator that has a selector and generic output. This would allow users to query only small portions of otherwise large JSON structures w/o having to deal with defining a type.
