Derive Enum Type should include values in FIFO order instead of LIFO.

I made a scala Enum

object Counts extends Enumeration {
  type CountsType = Value
  val Zero = Value(0)
  val One = Value(1)
  val Two = Value(2)
  val Three = Value(3)
}

Then created the same type for graph Ql schema

  val CountType = deriveEnumType[Counts.Value](
    IncludeValues("Zero", "One", "Two", "Three")
  )

or

  val CountType = deriveEnumType[Counts.Value](
    IncludeValues("Three", "Two","One","Zero")
  )

But found out that enum created was in LIFO so zero was assigned value 3 beacuse of this line

sangria/src/main/scala/sangria/macros/derive/DeriveEnumTypeMacro.scala

Line 126 in 0bf8053

case (acc, MacroIncludeValues(vals, _)) ⇒ acc ++ vals

When i run the introspection query i get three on the top of my enum values.

The best way to avoid this issue is to not use DeriveEnumType and create it like this
val Count = EnumType(
"Count",
values = List(
EnumValue("Zero", value = Counts.Zero),
EnumValue("One", value = Counts.One),
EnumValue("Two", value = Counts.Two),
EnumValue("Three", value = Counts.Three)
)
)
