Detailed Description

This is a truncated and private version of PageHeaderData.

Nothing other than the flags are needed in a meta file so we can use this to save space in the file directories. This is 4-bytes exactly and that means we can store 1023 PageNumber in a page directory, following the header.

Note: this must be kept in sync with PageHeaderData as a prefix of that.
