POC: prove the concept of local RPC via protobufs. 

This is an example of a jni call that accepts and returns proto objects. Ultimately, this trades a minor amount of performance for a significant improvement of ease of use. By exchanging protocol buffers, the Kotlin and Rust layers are able to communicate using far more complex objects. Eventually, this type of approach might completely replace the use of a database or sqlite.
