scan_ip6_flat - parse an IPv6 number in flat ASCII representation

       scan_ip6_flat  parses an IPv6 number in flat ASCII representation from src and writes the result into ip.
       It returns the number of bytes read from src or 0 if the parsing failed.

       scan_ip6_flat accepts upper and lower case hex letters.

       The flat representation should have been output by fmt_ip6_flat.

       #include <libowfat/str.h>
       #include <libowfat/ip6.h>

         char buf[]="00000000000000000000000000000001";
         char ip[16];
         if (scan_ip6_flat(buf,ip) != str_len(buf))
           parse_error();
