A faster URL dispatcher for aiohttp

The default `UrlDispatcher` implementation does a linear search every which can have a significant [TimeComplexity](https://wiki.python.org/moin/TimeComplexity) when dispatching urls when there are a lot of routes. `FastUrlDispatcher` keeps an index of the urls which allows for fast dispatch.

This library will become obsolete with aiohttp 3.10 as the changes
are expected to merge upstream via https://github.com/aio-libs/aiohttp/pull/7829

## Installation

Install this via pip (or your favourite package manager):

`pip install aiohttp-fast-url-dispatcher`

## Usage

Attach to a `web.Application` before any resources are registered.

```python
dispatcher = FastUrlDispatcher()
app = web.Application()
attach_fast_url_dispatcher(app, dispatcher)
```

Create with a new `web.Application`

```python
dispatcher = FastUrlDispatcher()
app = web.Application(router=dispatcher)
```

### Caveats

If you have multiple handlers that resolve to the same URL, this module will always prefer the static name over a dynamic name. For example:

```python
app.router.add_get(r"/second/{user}/info", handler)
app.router.add_get("/second/bob/info", handler)
```

`"/second/bob/info"` will always be matched before `r"/second/{user}/info"`
