add .patch case to JSONEncoding.default in APIClient

[cuylerquint]

Great repo 😄!! Attempted to push a branch and PR but got 'denied access' 🤕. would love to contribute! Took me a while to figure out why my server wasn't processing the request correctly but found out that patch wasn't using JSON encoding at default 😉

one liner in my attempted PR:

class func defaultEncoding(forMethod method: HTTPMethod) -> ParameterEncoding {
    switch method {
    case .post, .put:
      return JSONEncoding.default
    default:
      return URLEncoding.default
    }
  }

to

class func defaultEncoding(forMethod method: HTTPMethod) -> ParameterEncoding {
    switch method {
    case .post, .put, .patch:
      return JSONEncoding.default
    default:
      return URLEncoding.default
    }
  }
