Missing EU flag and inability to use alpha-2 codes

[mscno]

Hi, thanks for a great library.

Made it super easy to add flags to my phx app.

Two suggestions for improvements:

1. Add the ability to use alpha-2 codes. The alpha-2 codes are far more prevalent across all other geo tools and databases that I have ever worked with, and for me at least, alpha-2 codes are way more natural to work with.
2. The current focus on alpha-3 codes leaves out all the flags in flagpack that do not have a value defined for the alpha-3 column, example: The European Union flag, Rainbow flag etc. It would be great to have these included as well.

Hi @mscno, I really appreciate your feedback. It is great to hear that my library is being actively used. I did not know that alpha-2 codes are much more common as I do not work with geo-tools and databases often. I see your point about the European Union flag and the rainbow flag.

What do you think about a complete switch to alpha-2 function names? The flag/1 component could still support all types of codes: alpha-2, alpha-3 and numeric.

I would love that!

I think alpha-2 codes are the right way forward. And the generic flag/1 component would be a good way to keep support for alpha 3 codes if needed.
