Add StreamReader.total_raw_bytes to report the download progress

[robpats]

What do these changes do?

Currently it is not possible to get the real progress of downloading data. The closest thing is `StreamReader.total_bytes, but it could be the number of bytes of decompressed data. This pull request addresses this.

Are there changes in behavior for the user?

A new property StreamReader.total_raw_bytes can be used by the user.

Is it a substantial burden for the maintainers to support this?
