`zstd` vs. `zstandard`

[mtelka]

The piece of code in prereq.py claims there is namespace clash between zstd and zstandard, but after installing latest zstandard (version 0.21.0) I see no such clash:

$ pip install zstandard
...
$ cd ~/.local/
$ find . -type f
./lib/python3.9/site-packages/zstandard-0.21.0.dist-info/WHEEL

The zstandard project changed their primary module from zstd to zstandard long time ago (in version 0.9.0): https://github.com/indygreg/python-zstandard/commit/eda279a391e9d912ef33e55a50929770534f5df1
