[WIP] Fix issue in datamap for multiple blocklets across blocks
It is a rough fix, just give an idea of how to fix it.
Current datamap writing is mapped between block to blockletid, instead of
that we can map to carbonindex to blockletid, In this way, we can avoid the
extra mappings in datInstead amaps while reading. And it eases during writing
as datamap can completly eliminate the block concept in it.
