[Bug][Gfycat] "malformed" gfycat json throws KeyError - gfyName

[shinji257]

This one ended up being odd. It may even just be a one off but I thought to at least let you know. Please be aware this particular gfycat doesn't exist (as it turns out) so no lost data for me but I don't know if this means that some error checking should be handled on the script.

For those wanting to see a comparison here is a few:
A good api response: https://api.gfycat.com/v1/gfycats/harmoniousgentlecivet
This api response: https://api.gfycat.com/v1/gfycats/illexcitablehairstreak
A normal 404 response (I just removed the k): https://api.gfycat.com/v1/gfycats/illexcitablehairstrea

The values I find strange are nsfw and gatekeeper are 0 (or 1) for the good responses. On the bad one above it is 3. wtf does 3 mean? Also gfyNumber is 0 on the bad one. Maybe just treat gfyNumber == 0 == bad?

wtf does 3 mean?

"3" means "Possibly Offensive" according to the API docs:

Indicates if content is “safe for work” or not. 0 == Clean, 1 == Adult, 3 == Possibly Offensive
