This is a first step towards loading more stuff simultaneously rather than sequentially. The functional part of this is pretty small: call `calculateFetchPaths` and then `Promise.all(fetchPaths.map(loadFileFromURL));`. I also transposed the return type of `calculateFetchPaths` since it's more convenient to consume this way. I redid the logic in `calculateFetchPaths` a bit. I renamed `src/plugins/fetch.ts` to `calculateFetchPaths.ts` since the file performs no fetching. I also renamed `loadFromFile` to `loadFileFromURL`.
