feat!(sdk): Remove 'toFile' method

[dmihalcik-virtru]

This removes a dependency on streamsaver.js. The equivalent function to this method is now viewable in the App.tsx file:

async function toFile(
  stream: ReadableStream<Uint8Array>,
  filepath = 'download.tdf',
  options?: {
    encoding?: BufferEncoding;
    signal?: AbortSignal;
  }
): Promise<void> {

  const fileStream = streamsaver.createWriteStream(filepath, {
    writableStrategy: { highWaterMark: 1 },
    readableStrategy: { highWaterMark: 1 },
  });

  return stream.pipeTo(fileStream, options);
}
