Improve logic when to write column indexes

Currently, we always write column indexes. In case of the data is ordered (ASCENDING or DESCENDING) the filtering would highly benefit from column indexes. While, if the data is UNORDERED it is not obvious if ordering based on column indexes would make sense. For example if the data is random then the min/max values of the different pages might be close to each other so in most cases filtering based on these values would not drop any of the pages. In the other hand UNORDERED values does not mean that the values are random. It can happen that the values are clustered or semi-ordered. We shall discover these cases somehow before writing the column indexes and write only if the min/max values for the pages do not overlap too much.

Another simple case if we have only one page. In this case writing column indexes is useless.

まず、column-index の書き込み経路と、順序付きデータと順序なしデータをどのように扱うかを追跡します。単一ページのデータの場合と、ページの min/max の重複がある場合の動作を比較します。フィルタリングを改善できない場合に indexes が省略され、順序付き、順序なし、クラスタ化、および単一ページのケースがカバーされていれば完了です。
