Static-frame

Added explicit handling for binary operators applied to differently-sized ``IndexHierarchy``.

Refined behavior of ``Frame.from_concat_items`` when given tuples as labels; implemented support for tuples as labels in ``IndexLevels.values_at_depth``.

Refined behavior of ``names`` attribute on ``IndexBase`` to ensure that an appropriately sized iterable of labels is always returned.

Added ``IndexHour`` and ``IndexHourGO`` indices.

Added ``IndexMicrosecond`` and ``IndexMicrosecondGO`` indices.

Added support for ``round()`` on ``Series``.

``Index.astype`` now returns specialized ``datetime64`` ``Index`` objects when given an appropriate dtype.

``IndexHierarchy.astype`` now produces an ``IndexHierarchy`` with specialized ``datetime64`` ``Index`` objects when given an appropriate dtype.

Added ``IndexLevels.dtypes_at_depth()`` and ``IndexLevels.dtype_per_depth()`` to capture resolved dtypes per depth.

Added ``IndexLevels.values_at_depth()`` to capture resolved typed arrays per depth.

Updated ``IndexHierarchy.display()`` to display proper types per depth.

Refactored ``IndexLevel`` to lazily cache depth and length attributes.

Refactored ``IndexHierarchy`` to store a ``TypeBlocks`` instance instead of 2D array, permitting reuse of ``TypeBlocks`` functionality, columnar type preservation, and immutable array reuse.

Fixed flaw in ``IndexHierarchy.label_widths_at_depth``.

Fixed flaw in ``Frame.from_records`` and related routines whereby a ``NamedTuple`` in an iterable of length 1 was converted to a single-row, two-dimensional array.

Fixed flaw in ``Frame`` function application on iterators for some ``Index`` type configurations.

API documentation now shows full signatures for all functions.

Improvements to ``interface`` display, including in inclusion of function arguments and new "Assignment" category; improvements to API documentation.

Fixed issue in not handling mismatched size between index and values on ``Series`` initialization.

Fixed issue creating a datetime64 ``Index`` from another datetime64 ``Index`` when their dtypes differ.

Fixed an issue when passing an immutable ``Index`` as ``columns`` in ``FrameGO.reindex``.

Series`` default constructor now efficiently handles ``Series`` given as ``values``.

``Frame`` default constructor now efficiently handles ``Frame`` given as ``data``.

``AutoMap`` now serves as the core mapping structure for all ``Index`` object, offering better performance, immutability, and internal uniqueness checks.
