crypto.constants are missing #159 (#164)

* crypto.constants are missing #159

According to https://nodejs.org/dist/latest-v6.x/docs/api/crypto.html#crypto_crypto_constants I should be able to use crypto.constants.RSA_PKCS1_OAEP_PADDING with privateDecrypt.
Instead of using the constant I used it's value (4) instead and it works fine.

For now this includes only the constants of `Other OpenSSL Constants`

* update the tests

* further update tests
