Support for {0:02X}, 'y'

[tarwich]

I'm still getting an error here when calling fmt::format("{0:02X}", 'x'); and I think it's because it's not liking the number alignment, but... 'x' is a number in this case.

    // format.cc:444
    if (spec_.align_ == ALIGN_NUMERIC || spec_.flags_ != 0)
      throw FormatError("invalid format specifier for char");

I was able to patch it with this horrible code. If for some reason you like it, I can make a pull request.

Fixed, sorry for the inconvenience (I forgot to test the previous fix and of course it was not working as expected).

Thanks again!
