Generate enums closed-polymorphic classes, and use literal enum members as the discriminator

[aSemy]

I want to be able to use literal enum members to discriminate classes

https://www.typescriptlang.org/docs/handbook/enums.html#union-enums-and-enum-member-types

@Serializable
sealed class Project {
  abstract val name: String
}

@Serializable
class OwnedProject(override val name: String, val owner: String) : Project()

@Serializable
class DeprecatedProject(override val name: String, val reason: String) : Project()

fun main() {
  val tsGenerator = KxsTsGenerator()
  println(tsGenerator.generate(OwnedProject.serializer().descriptor))
}

should generate something like

enum ProjectKind {
  OwnedProject,
  DeprecatedProject,
}

interface Project {
  type: ProjectKind;
}

interface OwnedProject {
  type: ProjectKind.OwnedProject;
  name: string;
  owner: string;
}

interface DeprecatedProject {
  type: ProjectKind.DeprecatedProject;
  name: string;
  reason: string;
}
