ZIP64 Streaming Extraction Failure

[pathartl]

I've been able to pretty consistently replicate an issue extracting ZIP64's in a stream where it will extract all entries up until a >4GB file and then silently skip over every other entry.

I believe the issue may lie with how the header is read in StreamingZipHeaderFactory. From my limited testing it seems like it's trying to read the header for the next entry 16 bytes past the start of the actual header. This causes ZipHeaderFactory.ReadHeader to return null and stops reading more of the archive.

Definitely seems like a bug in the ZIP64 byte reading. Back to reading the spec. Maybe a bug in Reader vs Archive
