fix dynamic segments with URL-encoding

```js
decodeURI('/foo%20bar') // '/foo bar'
decodeURI('/foo%23bar') // '/foo%23bar'
decodeURI('/foo%3fbar') // '/foo%3fbar'

decodeURIComponent('/foo%20bar') // '/foo bar'
decodeURIComponent('/foo%23bar') // '/foo#bar'
decodeURIComponent('/foo%3fbar') // '/foo?bar'
```

This fixes two separate, but related problems:

 1. `router.add([{ path: '/foo bar?baz', }])` did not previously
    match `/foo%20%3fbaz`
 2. `router.add([{ path: '/foo/:bar', ... }])`, when given
    `/foo/a%20b%23c%3fd`, would return params `{ bar: 'a b%23c%3fd' }`
