Create a crypto stream to simplify the interface for creating encrypt and decrypt streams.

1. Create a new GnuPGCrypt
2. Create a new EncryptOnlyGnuPGCrypt. This is a simple decorator that will take an Crypt instance and call it for encrypt, but for decrypt, throw a RuntimeException saying this crypt can only be used for encrypting.
3. Add tests for it, you'll need to create your own pub private keys with the gpg CLI.
4. Add documentation in the README on how to use the two new crypts.

Please use the OO version of this library.

To actually use GnuPG, you need to create an instance. Then import pub and private key data (separately), then get the fingerprint for each, and then call addEncryptKey or addDecryptKey. The pub key is the encrypt key.

Once the instance is configured, you can then call encrypt/decrypt on data.

The GnuPGCrypt class constructor should just accept a fully configured GPG instance and assume it's been fully configured. Then you should have static method like createFromKeys($pub_key, $priv_key = null) and that will create a new gnu pg instance, and load the keys and throw an exception if anything is wrong. The private key is optional if they only want to use this library for encrypting. If no private key is given, then you need to wrap the created GnuPGCrypt in an EncryptOnlyCrypt.
