The task

For a small file, such as `file.byteLength === 100` with `{ minSize: 200 }`, the wrapper should read the whole source once with `file.slice(0, 100)`, then serve later calls like `slice(0, 10)` and `slice(50, 60)` from that cached whole buffer without calling the source again. For a larger file, such as…
