Alexa ruleset checker working
The ruleset checker seems to be working: it downloads and unzips the Alexa Top1M and automatically generates the git diff. Comparing the two seems to be working as well. Manually checked some rules: they seem to have been correctly identified as in the Top 1M and not in stable
