- update to 2.9.2:
  * optimize initialization from strings by not constantly
    resizing buffer
  * optimize util.hex2ba() and util.base2ba() by avoiding
    unnecessary copies
  * optimize util.base2ba() and util.ba2base() for n=16
    (hexadecimal)

- update to 2.9.1:
  * avoid buffer being unnecessarily initialized with 0s in
    several functions of the ``bitarray.util`` module
  * fix ``.count()`` type hint in pyi-file
  * improve testing
  * deprecate support for Python 2 - Python 2.7 support will be
    removed in bitarray version 3.0
  * ``bitarray(n)`` for integer initializer ``n`` will always
    return a bitarray of length ``n`` with all items initialized
    to ``0``
  * allow sub-bitarray in ``.count()``, `#212
  * add ``util.ones()`` ``.find()`` and ``.index()``:
    add keyword argument ``right`` for rightmost index
  * ``.itersearch()``: add start and stop argument, and keyword
  * argument ``right``
  * deprecate ``util.rindex()`` (will be removed in 3.0 release),
  * use ``.index(..., right=True)`` instead
  * deprecate ``util.make_endian()`` (will be removed in 3.0
    release),
  * use ``bitarray(..., endian=...)`` instead
