Subject: [PATCH] Add python-zstandard

Used to be an indirect dependency of Augur, until xopen removed it
and we pivoted to the stdlib/backport in
<https://github.com/nextstrain/augur/pull/2009>

Adding here to not disrupt use by pathogen builds and it is already
included in conda-base
<https://github.com/nextstrain/conda-base/blob/ede4fa7518fc4e0ccbb6801909f1ecaeef880a7c/src/meta.yaml#L85>
