adds ability to fetch details from opencagedata.com request

[winescout]

I needed to fish out more detail from the API response, so I coded this up. Do you think it's worthy to add to the mainline?

Hey @winescout, thanks for your contribution! I like the idea of adding more interesting info in the response of the library, given that OpenCage gives a lot of data.

I'm thinking if it makes sense to add this in the existing main functions (reverse/geocode) with another parameter that says that you want to expand the response. With this approach, we keep the existing API while opening it with the changes that you proposed to retrieve more information about the location.

What do you think? Do you want to work on this or shall I jump to your branch?

@dsantosmerino awesome. I went back and forth on the right approach here. Happy to do it that way. Something like: ??

OpenCagex.geocode("Passatge de la Pau, Barcelona", fields: [:timezone, :countrycode])

I need this too ! More specifically, I need a geocode call to also return bounds information for the requested name. This PR is 2 years+ old. Why was this not merged? Has the functionality been added by other means?
