Added support for geojson files using "application/vnd.geo+json" as the mime type

[MiniCodeMonkey]

Currently, it is not possible to process sources using the application/vnd.geo+json mime type, as a somewhat-random file extension is assigned instead of .json.

This change adds this additional mime type to the list of known mime types in the mimetypes python library.

Here's an example of a source that fails because of the incorrect file extension.

@iandees Is this cool to be merged in?

[iandees]

Yep, thanks!

It looks good to me! I am a bit confused about why the tests didn't run, but it’s a small-enough change that I’m not worried about them passing.

Thanks!
