openapi spec for non 200 responses

[jhsc]

To Reproduce
Not sure if this is a bug, or just not implemented yet but I noticed that when the openapi spec is generated there is no error responses. It just generated 200's responses, but in the case we want to have non 200 responses included in the openapi spec how would this be possible? Is there documentation how to generate error responses for handlers?

Expected behavior
For example I have this

"/login": {
      "post": {
        "description": "Authenticates User",
        "operationId": "POST /login:Handler",
        "requestBody": {
          "$ref": "#/components/requestBodies/LoginReq"
        },
        "responses": {
          "200": {
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/LoginResp"
                }
              }
            },
            "description": "OK"
          },
          "default": {
            "description": ""
          }
        },
        "summary": "Login",
        "tags": [
          "Login"
        ]
      }
    }

I would want to add to the responses spec

"responses": {
          "200": {
            ......
            },
           "401": {
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/BadResp"
                }
              }
            },
          },

We'll work on this after #64 ! In the meantime you can still build a response by using the operation given by fuego.Get
