add lumen support

[kluivert-queiroz]

Hi. Thanks for this great package. I needed to use this package at my work and here we use Lumen in one of our projects.

This PR do some slightly changes like:

• Use Carbon::now() instead of global helper now() provided by Laravel.
• Access the router object by getting it through app() instead of Router facade.
• Get the route name based on $request->route() type, in Laravel you can use getName() method but in Lumen you'd have an array with route's config and parameters.
• Removed the dispatchable trait on ShortUrlVisited event, Lumen doesn't have this trait. (May this cause any trouble?)

If there's something I should be aware of, please tell me.

Hey @kluivert-queiroz! I'm glad that you like the package and I'm happy that you're finding it useful :smile:

Unfortunately, I don't think this is something that I'll be able to pull in because I'm not really intending on supporting Lumen. However, if enough people think that it's worthwhile I might consider it in the future.
