Integrated ``arraykit.BlockIndex`` in ``TypeBlocks``, offering significant ``Frame`` performance improvements.
``via_dt`` will now raise if an NA is encountered and a ``fill_value`` is not provided.
Corrected issue in ``Quilt`` construction when component ``Frame`` have ``IndexHierarchy``.
Corrected issue when using an ``Index`` as a selector in ``via_fill_value().loc[]``.
Added ``ErrorInitColumns`` to better indicated failures in column ``Index`` construction.
