   This pull request intends to support skipping pages using the metadata. This is especially useful when page indexes are NOT present. Even so, We still need to think through the case that the page index is present.
   
   Here is what I think. When we have a page index, we will probably have a separate API to skip to a page at a particular offset. If a callback is defined, it would take effect via the NextPage calls. So we skip to a page at an offset, and when we call NextPage, it will return the next eligible page.
