Documenting the API

[iduartgomez]

Currently we should document throughtfully all the public types in the crates:

• https://docs.rs/locutus-stdlib/0.0.2/locutus_stdlib/#
• https://docs.rs/locutus/0.0.2/locutus/

Others from:

• https://docs.rs/releases/search?query=locutus

would also benefit, but we can improve that when we start working on the node network impl again.

We also need to find a solution for documenting and publishing the typescript API docs like cargo does with Rust in: https://github.com/freenet/locutus/tree/main/apps/stdlib
