OPENSSL_hexstr2buf_ex() decodes the hex string B<str> and places the
resulting string of bytes in the given I<buf>.
The character I<sep> is the separator between the bytes, which is normally ':',
Setting this to '\0' means that there is no seperator.
I<buf_n> gives the size of the buffer.
If I<buflen> is not NULL, it is filled in with the result length.
To find out how large the result will be, call this function with NULL
