[Feauture]: Add geo matchers (toBeGeoLatitude, toBeGeoLongitude)

[verdecchia]

Feature Request

Description:

Add geo matchers:

• toBeGeoLatitude
• toBeGeoLongitude

I've been using jest and jest-extended for long. Few months ago I needed to make geographic
assertions to a project I was working on but I didn't found anything already done so I wrote
some custom code in my project and later refactored and open sourced to a library
(https://www.npmjs.com/package/check-geographic-coordinates).

Other developers finded it useful and used it, some of them gave to me some feedbacks in
how to improve it, but I was missing the most important one, the jest assertion syntax integration.
So I decided to look at jest-exteded more in deep, not as the user I was, but as a developer
and I made this feature request. Looking backward I think I would used it directly with jest-extended.

Possible solution:
