URLs with many distinct segments fail to match

`adblock-rust` performs a rough matching step against requests by splitting the URL into tokens, hashing them, and then comparing against hashes from tokens in parsed filters.

There is an [upper limit](https://github.com/brave/adblock-rust/blob/master/src/utils.rs#L25) to the number of tokens that can be generated from a URL, after which point any additional tokens are ignored. This was likely put in place to limit the performance impact from maliciously crafted URLs.

As it turns out, this limit is insufficient for a small number of real-world requests.
