Log Message:
py-numba: updated to 0.47.0

Version 0.47.0
--------------

This release expands the capability of Numba in a number of important areas and
is also significant as it is the last major point release with support for
Python 2 and Python 3.5 included. The next release (0.48.0) will be for Python
3.6+ only!  (This follows NumPy's deprecation schedule as specified in
`NEP 29 <https://numpy.org/neps/nep-0029-deprecation_policy.html>`_.)

Highlights of core feature changes include:

* Full support for Python 3.8 (Siu Kwan Lam)
* Opt-in bounds checking (Aaron Meurer)
* Support for ``map``, ``filter`` and ``reduce`` (Stuart Archibald)

Intel also kindly sponsored research and development that lead to some exciting
new features:

* Initial support for basic ``try``/``except`` use (Siu Kwan Lam)
* The ability to pass functions created from closures/lambdas as arguments
  (Stuart Archibald)
* ``sorted`` and ``list.sort()`` now accept the ``key`` argument (Stuart
  Archibald and Siu Kwan Lam)
* A new compiler pass triggered through the use of the function
  ``numba.literal_unroll`` which permits iteration over heterogeneous tuples
  and constant lists of constants. (Stuart Archibald)

Enhancements from user contributed PRs (with thanks!):

* Ankit Mahato added a reference to a new talk on Numba at PyCon India 2019
* Brian Wignall kindly fixed some spelling mistakes and typos
* Denis Smirnov wrote numerous methods to considerable enhance string support
  including:

  * ``str.isspace()``

  ``str.isascii``

  * Implementing ``np.lcm``
  * Implement np.gcd and math.gcd
  * Make slice constructor more similar to python.
  * Added support for slice.indices

  dependency and add pre-commit hooks for ``flake8`` compliance.

* Marc Garcia fixed the ``numba.jit`` parameter name signature_or_function
* Marcelo Duarte Trevisani patched the llvmlite requirement to ``>=0.30.0``

  fixed some idle tests.
* Vyacheslav Smirnov Enable support for `str.istitle()``
