class RouteSubscriber in Taxonomy Views Integrator 8

Alters the route for using Taxonomy Views Integrator.

Views is allowed to alter and builds the routes first, and we then alter this route after the fact. The idea is so we can have multiple views that define `taxonomy/term/%` as the page path, and the settings form on the term/vocab let the user determine which view displays.

Otherwise, Views will always control the path, and that's not what we want.
