Feature request: optionally load hi-res version of gif

[skyegecko]

It seems that at the moment this extension always loads the low-res mobile version of the gif even if a higher res version is available. Would it be possible to have an option to load the high-res version instead?

As an example off the front page:

1. Clicking on https://gfycat.com/specificgreatindochinahogdeer-gaming
2. Loads video with address https://thumbs.gfycat.com/SpecificGreatIndochinahogdeer-mobile.mp4
3. While video https://giant.gfycat.com/SpecificGreatIndochinahogdeer.mp4 is available
