Sort a list by integer with Elixir

1. Fetch data from URL/li>
2. Split each new line into a list item/li>
3. Split each line into list items/li>
4. Find the six digit video id from the URL, it should be the first integer in http paths of: “c13.adrise.tv/04C0BF/v2/sources/content-owners/”, “c13.adrise.tv/04C0BF/ads/transcodes/”/li>
5. Group by Video ID/li>
6. Get Cache Hit and Misses for each Video/li>
7. Calculate the Cache Hit Misses
8. Sort by video id
