feat(client-verification): add client verification (#104)

New configurations:

- `CHECK_CLIENT_VERSION` enables the check (default=True)
- `CLIENT_VERSION_URLS` contains a chain of valid client hashes. [osu!](https://osu.ppy.sh/home/download) and [osu! GU](https://github.com/GooGuTeam/osu/releases) are valid by default. View [g0v0-client-versions](https://github.com/GooGuTeam/g0v0-client-versions) to learn how to support your own client.
