Printing an InversionList looks like this:
writefln("%s", CodepointSet('a', 'z'));
=>
[97..122)

I'd like to request that InversionList support *some* formating options, in
particular, 'x' and 'X', and optionally, width. hex would be prefixed with 0x.
This would allow printing as:
writefln("%04x", CodepointSet('a', 'z'));
=>
[0x0061..0x007b)

This would be helpful, as codepoints are often used hex style, and not decimal
style.
