Given that all the methods are already asynchronous we can just use `await` more throughout this code, rather than having to explicitly return function-calls and `undefined`. Note also how none of the `ObjectLoader.prototype.load` call-sites use the return value.
The `ObjectLoader.prototype.load` method has a fast-path, which avoids any lookup/parsing if the entire PDF document is already loaded. However, we still need to create an `ObjectLoader`-instance which seems unnecessary in that case. Hence we introduce a *static* `ObjectLoader.load` method, which will help avoid creating `ObjectLoader`-instances needlessly and also (slightly) shortens the call-sites. To ensure that the new method will be used, we extend the `no-restricted-syntax` ESLint rule to "forbid" direct usage of `new ObjectLoader()`.
