MCOL-4566: Add rebuildEM tool support to work with compressed files.

Browse Source 
* This patch adds rebuildEM tool support to work with compressed files.
* This patch increases a version of the file header.

Note: Default version of the `rebuildEM` tool was using very old API,
those functions are not present currently. So `rebuildEM` will not work with
files created without compression, because we cannot deduce some info which are
needed to create column extent.
