/**
 * @internal
 *
 * A FileBlob is a replacement for the Blob class that allows to lazy read files
 * in order to preserve memory.
 *
 * It is a drop-in replacement for the Blob class, so you can use it as a Blob.
 *
 * The main difference is the instantiation, which is done asynchronously using the `FileBlob.create` method.
 *
 * @example
 * const fileBlob = await FileBlob.create("path/to/package.json");
 *
 * await fetch("https://aschen.tech", { method: "POST", body: fileBlob });
