Add way to navigate to search from the series list

[Chesire]

There should be some sort of way to navigate straight to search from the series list, to make it a bit easier to show how new series can be tracked. This could be a FAB on the series list itself that links into the search flow.

I think this will require some sort off communication from the app-series module into the app module activity, then from there it can reach out to the app-search module. Failing that maybe something could be done with a deep link?

Search could maybe sit under the "app-series" module, since it will primarily be used to search for new series and add them to the list of tracked series.
This would make navigation to it a lot easier, and it would still make sense.

Failing that, staying as a new module, but having some way for the app-series to navigate into it, instead of it being its own section in the navigation drawer.

A top level navigator from the app module makes sense - then this can be injected into the series so when the button is tapped it requests the navigation via this navigator.
