Factory function that instantiates an RSA_pub object from a (e, n) tuple.
'e' is the RSA public exponent; it is a string in OpenSSL's binary format,
i.e., a number of bytes in big-endian.
'n' is the RSA composite of primes; it is a string in OpenSSL's
binary format, i.e., a number of bytes in big-endian.
