zstandard: vendor python-zstandard 0.13.0

Version 0.13.0 of the package was just released. It contains
an upgraded zstd C library which can result in some performance
wins, official support for Python 3.8, and a blackened code base.

There were no meaningful code or functionality changes in this
release of python-zstandard: just reformatting and an upgraded
zstd library version. So the diff seems much larger than what it
is.

Files were added without modifications.

The clang-format-ignorelist file was updated to reflect a new
header file in the zstd distribution.

# no-check-commit because 3rd party code has different style guidelines

  require use of ``CompressionParameters``.
* Expose ``ZSTD_getFrameProgression()`` from more compressor types.
* Support modifying compression parameters mid operation when supported by
  zstd API.
* Expose ``ZSTD_CLEVEL_DEFAULT`` constant.
* Support ``ZSTD_p_forceAttachDict`` compression parameter.
* Support ``ZSTD_c_literalCompressionMode `` compression parameter.
* Use ``ZSTD_CCtx_getParameter()``/``ZSTD_CCtxParam_getParameter()`` for retrieving
  compression parameters.
* Consider exposing ``ZSTDMT_toFlushNow()``.
* Expose ``ZDICT_trainFromBuffer_fastCover()``,
  ``ZDICT_optimizeTrainFromBuffer_fastCover``.
* Expose and enforce ``ZSTD_minCLevel()`` for minimum compression level.
* Consider a ``chunker()`` API for decompression.
* Consider stats for ``chunker()`` API, including finding the last consumed
  offset of input data.
* Consider exposing ``ZSTD_cParam_getBounds()`` and

---------------------------------------

* Support for block compression APIs.
* API for ensuring max memory ceiling isn't exceeded.
* Move off nose for testing.

Changes
-------

* ``pytest-xdist`` ``pytest`` extension is now installed so tests can be
  run in parallel.
* CI now builds ``manylinux2010`` and ``manylinux2014`` binary wheels
  instead of a mix of ``manylinux2010`` and ``manylinux1``.
* Official support for Python 3.8 has been added.
* Bundled zstandard library upgraded from 1.4.3 to 1.4.4.
* Python code has been reformatted with black.
