Improve twitter rule

[liamengland1]

https://pbs.twimg.com/media/EnlTOuPVkAEVFcG?format=jpg&name=900x900 should redirect to https://pbs.twimg.com/media/EnlTOuPVkAEVFcG?format=jpg&name=medium

https://pbs.twimg.com/media/EnlTOuPVkAEVFcG.jpg?name=medium is 404

Perhaps the userscript should check the ?format=jpg&name=whatever urls as well as the .jpg?name=whatever urls?

Thanks for reporting! I decided to take the opportunity to improve the twitter rule a bit as well. As someone else noted in the issue, it does appear like twitter's trying to phase out the .jpg and instead go for format=jpg, so I decided to just automatically go in that direction, rather than double the amount of queries (there can already be an absurd amount of queries for tweet images, especially for images like that where medium is the largest size available).

To avoid the .jpeg issue when saving, I set it to have a custom filename, replacing jpeg with jpg.
