values is not generated for enums with open case

Problem

Hi!

A common pattern when creating enums is to define value field and leave one case open.

When defining such patterns you still need basic values. This is one of greatest features of enumeratum and it is missing in stdlib.

I think there was a reason why this was done like this, but it would be great to somehow support it out of the box.

Other thing to improve is to make valueOf bounded to this custom value for basic cases.

Is this possible?

Minimized code

enum Segment(val value: String):
  case Literal(override val value: String) extends Segment(value)
  case One extends Segment("*")

object Segment:
  def valueOf(value: String): Segment =
    Segment.values.find(_.value == value).getOrElse(Literal(value))

Output

[error] 14 |    Segment.values.find(_.value == value).getOrElse(Literal(value))
[error]    |    ^^^^^^^^^^^^^^
[error]    |value values is not a member of object ru.tinkoff.sso.commons.authorization.model.Segment - did you mean Segment.valueOf?
[error]    |Although class Segment is an enum, it has non-singleton cases,
[error]    |meaning a values array is not defined

Expectation

//compiles and contains basic cases
Segment.values == Array(Segment.One)

Segment.valueOf("*") == Segment.One

The original reasoning was that values is exhaustive rather than "whatever values are defined" I'm sure we can make it opt in, but there are also I guess library solutions to this if we don't make it configurable
