Static-frame

Series.isna()``, ``Series.dropna()``, and related functions now properly handle arrays that contain objects such as ``Frame`` or ``np.ndarray`` that raise for usage of ``__bool__()``.

Set ``arraykit`` version to 0.2.9: ``isna_element`` now identifies ``pd.Timestamp('nat')`` as a NA value, and invalid ``datetime64`` strings given to ``Frame.from_delimited`` and related interfaces now properly raise exceptions.

Corrected issue in ``IndexHierarchy.label_widths_at_depth()`` which caused incorrect cell merging in XLSX output when ``merge_hierarchical_labels`` is True.

Corrected issue in ``Series.dropna()`` whereby full drops would not retain the index class.

Performance enhancement to ``TypeBlocks.equals()`` and related routines using ``arrays_equal()``.

Significant performance optimizations to ``IndexHierarchy`` set operations, as well as optimized pathways for determining ``TypeBlocks`` equality.

JSON metadata in NPY and NPZ encodings of ``Frame`` data now properly encodes and decodes ``np.datetime64`` and ``datetime.date`` objects.

Corrected issue on Python 3.11 in the creation of ``memory`` displays due to usage of ``Enum``.

Corrected issue in ``Frame.relabel_shift_out()`` where ``index_constructors`` are not assigned to subset index.

Extended ``Frame.iter_tuple()`` ``constructor`` argument to support ``dataclass``-created classes.

Corrected handling of 0-sized containers in ``Frame.insert_before()`` and ``Frame.insert_after()``.

Corrected issue with some ``IndexHierarchy`` formations when using slices in an ``HLoc`` with more than one depth selection.

Added ``Frame.consolidate`` interface, including ``Frame.consolidate[]`` and ``Frame.consolidate.status``.

Added ``Quilt.bus`` property.

``IndexHierarchy.rehierarch()`` and related routines now correctly reorder index constructors by default.

Added ``index_constructors`` arguments to ``IndexHierarchy.rehierarch()``, ``Series.rehierarch()``, ``Bus.rehierarch()``, ``Yarn.rehierarch()``.

Added ``index_constructors``, ``columns_constructors`` arguments to ``Frame.rehierarch()``.
