This implements Selective functor for `Either[A, B]` "task" (`Initialize[Task[Either[A, B]]]`).
The selective functor allows an encoding of if-expression:
```
def ifS[A](
x: Def.Initialize[Task[Boolean]]
)(t: Def.Initialize[Task[A]])(e: Def.Initialize[Task[A]]): Def.Initialize[Task[A]]
```
The benefit of this approach is that task dependencies are still visible to inspect command.
