This enables a ReadableStream to be obtained for a file, which can then
be handled with e.g. https://github.com/MattiasBuelens/wasm-streams

let file: web_sys::File = ...;
let stream = wasm_streams::readable::ReadableStream::from(
    file.stream()
        .unchecked_into::<wasm_streams::readable::sys::ReadableStream>(),
);

The build failures don't seem related to this PR, it seems to be related to the recent change to rename anyref to externref.
