FEATURE REQUEST: Allow customised CountrySelector

[AnderUstarroz]

While this library is lightweight and works great, is not very customisable in terms of aspect, many customers don't like displaying flags within their inputs but this library leaves not alternative. CountrySelector just displays a flag, it would be great if also allows displaying either the country name or country prefix.

Proposed solution
Add option to CountrySelector called display where the allowed options are:

• Flag (default)
• Name
• Prefix

For instance:

Although a perfect solution would be allowing all possible combination of those (flag. + name), (flag + prefix), (flag. + name + prefix), (name + prefix), etc..)

Flag + Name + Prefix:

Would be as easy as adding the new display property within the Country selector API, and making FlagImage optional.

I fixed this at my PR

But I don't have time to write the tests and follow the guidelines. I'll publish it as personal package and add it here

You can see it working here: https://react-international-phone-git-e93393-yurii-brusentsovs-projects.vercel.app/?path=/story/phoneinput--with-order

Also, I added a new customArrow prop: https://react-international-phone-git-e93393-yurii-brusentsovs-projects.vercel.app/?path=/story/phoneinput--with-custom-arrow
