Union class

An SumType that contains every type defined by taking the DataAnnotation.typeParams and applying them to every key in the body.

Each key generates the corresponding class, every one of them with an unnamed constructor that requires every argument from the respective value in body.

The visit function, used to destructure the union is configured by deriveMode, and optionally an top level version of it is generated, according to topLevel.

The structural implements flag controls whether or not union cases that match structurally will be implemented in other cases
