integer backed enums are stored as integer properties as opposed to enums

The issue is that an OpenAPI definition containing something like:

        enum_integer:
          type: integer
          format: int32
          enum:
            - 1
            - 2

...will result in code that looks like:

    public var enumInteger: Int?

That example is from the unit tests:

CreateAPI/Tests/Support/Specs/edgecases.yaml

Lines 1097 to 1102 in 0069e8b

	enum_integer:
	type: integer
	format: int32
	enum:
	- 1
	- -1

I would prefer/expect to see something more like:

    public enum EnumInteger: Int, Codable {
        case _1 = 1
        case _2 = 2
    }

I'm assuming this was a choice, probably? But maybe there could be a flag for it or something?

No doubt the negative number complicates things. 😂
