A tiny example of calling Lean's FFI from Rust with Nix.
This is based on:
* [Lean4 Reverse FFI](https://github.com/leanprover/lean4/tree/master/src/lake/examples/reverse-ffi)
* [Lean4 FFI](https://lean-lang.org/lean4/doc/dev/ffi.html#initialization)
* [Rustonomicon FFI](https://doc.rust-lang.org/nomicon/ffi.html)
