Modules built using Rust/WASM [ON DEMAND]

[bajtos]

Some of the work required to make this happen:

• Tooling for building a Rust project for Station. This will likely involve Deno’s wasmbuild and possibly other build steps. A minimal solution is to write documentation explaining the manual steps.
• SDK exposing Zinnia Platform APIs. This can be a light wrapper around js_sys and web_sys crates, plus functions using wasm-bindgen to invoke our custom APIs, e.g. libp2p, Activity Log reporting, and so on.
• Zinnia CLI need to know how to load and run these modules.
• Documentation for module builders

Nice to have: investigate options provided by Deno to optimise ops invocations from WASM. https://crates.io/crates/deno_ops#user-content-wasm-calls
