 Streams the diff of two object lists, ideal for large lists and maximum performance.
 
+ℹ️ `streamListDiff` requires ESM support. For browser usage, it will work out of the box if you use a modern bundler (Webpack, Rollup) or JavaScript framework (Next.js, Vue.js). For Node.js, just add `"type": "module"` in your package.json.

   - `chunksSize` the number of object diffs returned by each streamed chunk. (e.g. `0` = 1 object diff per chunk, `10` = 10 object diffs per chunk).
   - `showOnly` gives you the option to return only the values whose status you are interested in (e.g. `["added", "equal"]`).
   - `considerMoveAsUpdate`: if set to `true` a `moved` value will be considered as `updated`.
+  - `useWorker`: if set to `true`, the diff will be run in a worker for maximum performance. Only recommended for large lists (e.g. +100,000 items).
