C++ Hybrid Encryption CLI

This is a command-line tool that can generate Hybrid Encryption keys, and encrypt and decrypt using Hybrid encryption.

It demonstrates the basic steps of using Tink, namely loading key material, obtaining a primitive, and using the primitive to do crypto.

Moreover, since this app shares the same Bazel WORKSPACE with Tink, its BUILD file can directly depend on Tink.
