The library file zstd.cpython-38-x86_64-linux-gnu.so (on my Python 3.8 Linux PC) is installed globally in site-packages instead of in the zstandard/ package directory. This means it can conflict with other packages which install something similar.

In particular, it conflicts with the zstd Python package, which installs its library to the same file. Because zstandard vendors its own version of zstd, the library should be moved into zstandard/ with the rest of the package.
