Implement extra parameters

[lcobucci]

This introduces the possibility of providing extra parameters during route registration (such as route name) and by default registers the unparsed route as an item on the list.

Fixes #225
Fixes #234

Alternative to #265

Still a draft because I'm looking for ways to reduce the performance impact (~20% on static routes 😭):

The performance impact is inevitable due to the need to return the extra parameters on the result.
I'll look into optimising things more as soon as we have a more stable API.
