Make the ResultWire injectable parameter of the BaseRouter class

The idea of PR - is to be able to inject the shared instance of ResultWire into separate Routers in order to send and receive the results across them.

I need this option to support complicated navigation cases in the multi-module project with bottom navigation where I need to keep several routers in parallel.

Since the constructor of the Router class has default implementation - the change is fully compatible with previous versions and should not break and library usage

This is how our case looks. From each of the tabs in the bottom nav, I would like to open LoginActivity and receive the results from it.
The idea is to have a shared instance of ResultWire and inject it into the Routers of each tab and the Login Activity.

Another option is to allow overriding of the methods setResultListener and sendResult. This will provide an option to implement this logic the way I want without having to use ResultWire at all
