Flag emoji for Python.
Converts flag emoji to ASCII and other way round.

This is based on http://schinckel.net/2015/10/29/unicode-flags-in-python/ by schinckel

All the flag emoji are actually composed of two unicode letters. These are the 26 regional indicator symbols.

Alone they look like this:
🇦 🇧 🇨 🇩 🇪 🇫 🇬 🇭 🇮 🇯 🇰 🇱 🇲 🇳 🇴 🇵 🇶 🇷 🇸 🇹 🇺 🇻 🇼 🇽 🇾 🇿

If you pair them up according to ISO 3166 some browsers and phones will display a flag.
For example TW is Taiwan: 🇹 + 🇼 = 🇹🇼

So, to encode an ASCII code like :TW: to 🇹🇼, we just need to convert the ASCII T and W to the corresponding regional indicator symbols 🇹 and 🇼.
To reverse it, we translate the regional indicator symbols back to ASCII letters.

    >>> import flag
    
    >>> flag.flag("IL")
    '🇮🇱'
    
    >>> flag.flag("GBENG")
    '🏴󠁧󠁢󠁥󠁮󠁧󠁿'
    
    >>> flag.flagize("Flag of Israel :IL:")
    'Flag of Israel 🇮🇱'
    
    >>> flag.dflagize("Flag of Israel 🇮🇱")
    'Flag of Israel :IL:'
    
    >>> flag.flagize("England :gb-eng: is part of the UK :GB:", subregions=True)
    'England 🏴󠁧󠁢󠁥󠁮󠁧󠁿 is part of the UK 🇬🇧'
    
    >>> flag.dflagize("England 🏴󠁧󠁢󠁥󠁮󠁧󠁿 is part of the UK 🇬🇧", subregions=True)
    'England :gb-eng: is part of the UK :GB:'

    >>> my_flags = flag.Flag(only_supported=True, allow_subregions=True)
    >>> my_flags.flagize("Convert actual flags like :US: but not unsupported ones like :XX:")
    'Convert actual flags like 🇺🇸 but not unsupported ones like :XX:'
