All pre-converted lineages are hosted on ncbitax2lin-lineages, a GitLab repo, which allows pushing larger files without Git LFS and a bigger repo size limit. Regeneration is straightforward, but it may incur quite a bit of memory (~20 GB). I generated lineages.csv.gz on a machine with 32 GB memory. Pull request on refactoring to a lower memory usage is welcome. It's mainly about this line, where the pool.map takes places.
