Add support for jfif files

[JBac]

Hi,

Any chance the jfif extension could be added to the typeMap?
I believe it just has the mime type of image/jpeg.

Thanks!

Hi @JBac! 👋🏻

The file is generated from mime-db, which in turn is compiled from IANA, Apache and nginx's MIME types.

If you're able to get the entry into mime-db, maybe in custom-types.json, it'll automatically trickle into this library 😄

BTW, looks like they've already requested some documentation for jfif; https://github.com/jshttp/mime-db/issues/177.

Still no .jfif "support". I know this list is generated directly from mime-db, which compiles from the three aforementioned sources, and this extension is not registered in any of them, but the JFIF files are handled as "image/jpeg" by all browsers and even in official sources: https://www.w3.org/Graphics/JPEG/

I'm actually adding it manually, but it would be nice to have this already packed in MimeTypes :-) Adding a post-download process to add a few common mime-types if they are missing would be great. Basically that's what I'm currently doing on my code, but I believe most people will have "faith" that this list is mostly inclusive, while, in fact, a somewhat common image format if missing :-(

Looks like there's a PR for it already; jshttp/mime-db#291 ☺️
