Building using Nx

Nx is used as the build system as the repository contains WebAssembly as well as Rust projects. Once the prerequisites have been installed, run the following commands. This will install the required Node.js modules, build the Rust and TypeScript projects, and finally produce a .vsix package that can be installed into Visual Studio Code.

npm ci
npm run build
npm run package
