feat(mount): use a sophisticated route matcher

The [`matchit`](https://github.com/ibraheemdev/matchit) crate is a real
lifesaver...

Before this commit, I had manually implemented a dynamic pattern matcher
for routes (which only supported one pattern per route) that worked; just
not very well. While searching for a way to implement multiple patterns
per route, I landed upon two crates:
[`matchit`](https://github.com/ibraheemdev/matchit) and
[`urlmatch`](https://github.com/SergeiMinaev/urlmatch). Ultimately, I
settled with `matchit` because it seemed a lot more mature and supported
nearly everything which I was looked for!
