This will reduce the impact of checksum/version collisions, as a
collision would have to happen between two indexes of the same archive
rather than any two indexes.

These effectively duplicate the master index tables, but in a less
flexible manner - as they don't support importing a master index where
some of the indexes are missing.
This commit also combines MasterIndexImporter with CacheImporter, to
make it easier to re-use code.
