Creates a DataTable|Set instance using an index of
archive data.
/**
* Returns archive data as a DataTable indexed by metadata. Indexed data will
* be represented by Map instances. Each DataTable will have
* its subtable IDs set.
*
* This function will only work if blob data was loaded and only one record
* was loaded (not including subtables of the record).
*
* @param array $resultIndices An array mapping metadata names to pretty labels
* for them. Each archive data row will be indexed
* by the metadata specified here.
*
* Eg, array('site' => 'idSite', 'period' => 'Date')
* @param int|null $idSubTable The subtable to return.
* @param int|null $depth max depth for subtables.
* @param bool $addMetadataSubTableId Whether to add the DB subtable ID as metadata
* to each datatable, or not.
* @throws Exception
* @return DataTable|DataTable\Map
