Class PositionWrapperStream
Namespace: Casewhere.Common
Assembly: Casewhere.Common.dll
Reading Position should be supported only for seekable streams, but ZipArchive seems to require this even from non-seekable streams, which is a bug (This bug fixed on .NET Core 2.0). So, we need to do to support writing ZIP files directly to OutputStream is to wrap it in a custom Stream that supports getting Position.
