When doing a LargeFile transfer using

await client.DownloadAsync(req, stream, progress, cancel);

the callback on ICopyProgress will only provide BytesTransfered, BytesExpected that are related against the Chunk/part .... not the overall progress of the file.

There is no way to get the number of chunks, the size of chunks/parts, nor get a running total of bytes across all the chunks.

This makes the progress report usesless for LargeFiles.
