Add next.jdbc plan to the api

[arichiardi]

The library expose a way to use transducers when transforming result sets: a function called plan.
This is very handy and one of the main features of next.jdbc.

Describe the solution you'd like
Add next.jdbc/plan to the api. There might be a bit of spelunking because of the implementation but it might doable.

Describe alternatives you've considered
Post process results sets.

I'm afraid this isn't possible due to the nature of pods, unless you can provide a string/EDN version of the function that should be applied to the result set. Would that be a reasonable compromise?

I personally like how zprint does it - basically you specify a function in its .edn file

This could be added to bb.edn with some kind of keyword wrapping it or something...not sure...it can be an extension mechanism for contributing to pods
