Description

Currently LegacyShallowIndexedEntry only supports reading from legacy format. We should add support to writing in old format (!format.storeRows()).

There are two cases to consider: RowIndexEntry (when the index is smaller than column_index_size_in_kb) and IndexedEntry (otherwise).

We should add tests to verify that the index is being properly converted from the current version to the legacy version.
