Support for "x-enumNames" in enum definitions

[bennycode]

I found this StackOverflow question which wants to create an interface for Color based on the following JSON input:

{
  // ...
  "definitions": {
    "Color": {
      "description": "",
      "enum": [
        0,
        1,
        2
      ],
      "type": "integer",
      "x-enumNames": [
        "RED",
        "GREEN",
        "BLUE"
      ]
    }
  }
}

The expected result is:

export enum Color {
    RED = 0,
    GREEN = 1,
    BLUE = 2,
}

But swaxios 0.1.2 generates:

/* tslint:disable */

/**
 * This file was automatically generated by "Swaxios".
 * It should not be modified by hand.
 */

export type Color = number;

Complete input file:

The x-enumNames property is a custom property (indicated by the leading x-) but it seems to be very popular because it has been asked for in many other projects before:

• Suggestion: Support x-enumNames extension Redocly/redoc#234
• How to generate enums along with the int -> string mapping RicoSuter/NSwag#1993
• Question: x-enumNames is not used to display possible string enum values for documentation? bootprint/bootprint-openapi#94
• x-enumNames domaindrivendev/Swashbuckle.WebApi#1287
• v6 annotation: named enumerations json-schema-org/json-schema-spec#57
• Support x-enumNames for integer enums swagger-api/swagger-ui#5272

I am sorry. I don't have time at the moment to care for this project too much. If you want to open PR for this issue, please had over to the bootprint-monorepo repository. It contains the latest versions of all bootprint projects.

The issue in bootprint-openapi describes the location where to fix it.
