[REQ] [Axios-Typescript] Create enumerator for parameters

Is your feature request related to a problem? Please describe.

When we have some parameter which is a enum, the generator is not creating and enumerator which can be used as a model. For example, for the following parameter (imageType) which is an enumerator:

/v1/users/settings/photo:
    get:
      operationId: getUserPhoto
      summary: Get User Photo
      tags:
        - Users
      parameters:
        - name: imageType
          in: query
          type: string
          enum:
            - b64
            - uri

It generates the following code:

getUserPhoto(imageType?: 'b64' | 'uri', options: any = {}): RequestArgs {
...

and it should generate something like this:

import { imageTypeEnum } from 'api/models' // pseudo import

getUserPhoto(imageType?: imageTypeEnum, options: any = {}): RequestArgs {
...

No file or test is named. Start by locating the Axios TypeScript generator and its handling of inline enum query parameters; compare generated output with the issue's example. Done means enum parameters are represented by an exported model and used in the generated method signature.
