 Users can audit the HTTP requests and responses being made by the library by setting the `Hooks` property of a `Client` with a set of event subscriptions. Available subscriptions include:
 
 - `RequestHookEventSubscriber` - Called before an HTTP request is made. A `RequestHookEvent` object, containing details about the request that will be sent to the server, is passed to the subscription's `RequestHookEventSubscriberCallback`
