Guide for compiler-developers about lunatic HOT 1 OPEN

So, the Rust, AssemblyScript, and Grain bindings each work by using WebAssembly function imports that the Lunatic runtime provides to each WebAssembly module.

The signatures for all of those function imports can be found here: https://github.com/lunatic-solutions/lunatic-rs/blob/main/src/host/api.rs

These are in Rust, but these are low-level ABI definitions, wrapped in an extern "C" block, meaning that these function signatures are similar to the signatures of those WebAssembly host imports.

If you wanted to target Lunatic as a runtime in your language for starters, you'd need to import these same host functions and integrate them into a higher-level Lunatic API in your language.
