@SimpleCoderr, what about the area codes starting with 840? Aren't they Abkhazian too?

[SimpleCoderr]

@ArtyomVancyan I added codes starting with 840, and also added 840 23, since some sources mention it.

Before I merge, we have another problem. Abkhazia is still considered a part of Georgia. Although there are Russian phone numbers in Abkhazia, the flag of the country is missing from the global countries' list. See stylesheet.json. If you can find the flag and add the styles with the right coordinates, we can merge this. Otherwise, this will be redundant, as when typing an Abkhazian phone number, it won't show a flag.

@ArtyomVancyan, I did not find the flag of Abkhazia in base64 from stylesheet.json, I have an idea to add the flag of this country to the sprite image at the end of all countries manually, but you probably won't agree to that)

Yeah, it will be inappropriate. Currently, if you type the Georgian phone numbers for Abkhazia, it will show the Georgian flag, and it will work similarly for Russian phone numbers.

Thanks anyway for the suggestion and your last contribution :)
