Oats can't handle complex types as query parameters

[glinton]

If using something as simple as an array, oats' generated code results in any.

For example, the following swagger generates this interface:

export interface GetStuffParams {
  query?: {
    stuffFilter?: string
    stuffFilterComplex?: any
  }
}
