It would speed up builds if boa used zstd for package index downloads when available. Micromamba does this for a few months now, someone is working on getting it into mamba at the moment, see https://github.com/mamba-org/mamba/issues/2523 for context

This could shave off ~10 seconds when downloading the conda-forge/osx-64 index for example.
