VSCode still gives an error
We had to set the type to module to get the `import` to work. Setting .mjs
didn't work (eslint didn't recognize the file). Setting the type to module
should be (based on my current understanding) not affect us negatively since we
are exporting a TypeScript library not a bundled one, and all the other source
files apart from this are intended to be `*.ts`.
