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 Differential Revision: https://phab.mercurial-scm.org/D7770
