Automatic result type composition

[benedeki]

Background

Slick requires an (implicit) converter to return a more complex class from a query result. That is cumbersome.

Feature

Add the ability of automatic conversion to query results if a case class type is provided

Slick is out of scope for us now. Closing. Can be reopened if there is a need to implement it. Doobie solves for it.
