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
