-------------------------------------
Description:
*Notes*
Description may not be complete.
*Goal*
To implement the new checkpoint (described in IGNITE-15818), we need to modify *FilePageStore*, a list (in reverse order) of *DelataFilePageStore* will be added to its structure, which will increase after each checkpoint (at its completion) and decrease after each merge with the *FilePageStore* by "compacter".
*DelataFilePageStore* will contain:
* Sorted list of *pageId*s: allows by binary search to find the offset in this file for the requested *pageId*;
* Allocation Index: *pageId* of the last allocated page;
* Pages themselves are sorted by *pageId*.
