Improve rule lookup performance (#4)

* Run test in parallel

* Improve rule lookup performance

Previously, it used to do a lookup by removing the last character of the
agent one by one until it found a match. This is really inefficient.

Instead, we now reverse the agents before storing and we remove the
first character one by one instead of the last.

* Format the configuration

* Switch clause to remove pattern
