Refactoring use/preload and more (#215)

* Drop `initPerformance` (closes #207)
* Cleaning up the use/preload types
* Use my good friend `Proxy` to allow access to both the `serviceProps` and the initialized instance without double calling (e.g, `useAuth()()`)
* More checks against double initializing
* Added binding to the initialize call (closes #213)
* `SuspenseWithPerf` now lazy loads performance monitoring and uses the user timing API
* Fixed the CJS build with a better external test (closes #214)
