[Bug] Enums with quotes in the value throw errors

[MattTaylorQuodd]

Reproduction:

npx swagger-typescript-api -p https://id.casdoor.com/swagger/swagger.json -o ./casdoor

Results:

SyntaxError: An enum member name must be followed by a ',', '=', or '}'. (661:48)
  659 |  */
  660 |   export enum ObjectSubscriptionState {
> 661 |   SubStatePendingPending = "SubStatePending = "Pending"",
      |                                                ^
  662 |   SubStateErrorError = "SubStateError = "Error"",
  663 |   SubStateSuspendedSuspended = "SubStateSuspended = "Suspended"",
  664 |   SubStateActiveActive = "SubStateActive = "Active"",

I think there is some kind of quote escaping rule that is failing here. the JSON has "SubStatePending = \"Pending\"", and I would expect to see the same thing in this output.
