ECC GF(p) point multiplication (from the NIST curves)
@param k The integer to multiply the point by
@param G The point to multiply
@param R The destination for kG
@param modulus The modulus for the field
@param map Boolean indicated whether to map back to affine or not (can be ignored if you work in affine only)
@return CRYPT_OK on success
