A path to a module that will be used to install the instrumentation.
The installModule is guaranteed to run before the rxjs module.
The primary job of the installModule is to call the @rxjs-insights/core install function.
It can be done directly, by importing the install function and calling it (which allows for specifying a custom recorder, tracer and locator), or indirectly, by importing the default installModule, e.g. @rxjs-insight/rxjs7.
The secondary job of the installModule is to set up the environment for the RxJS Insights, e.g. to install the Zone.js for better tracking of asynchronous actions.
By default, the installModule resolves to the @rxjs-insights/rxjs<version> module, e.g. for RxJS 7 it will be resolved to @rxjs-insights/rxjs7.
