replicated locally!

Per Luiz on slack:

hmm, the storage column was added to support adding signatures to the same rocksdb index, but it should be auto-created (empty) if you don't internalize the signatures
it's around here: https://github.com/sourmash-bio/sourmash/blob/b499152d9405256764cd288b690c162a88e14d03/src/core/src/index/revindex/disk_revindex.rs#L131-L133

let me check if the plugin is trying to open the DB as read-only
hmm, yes:

sourmash_plugin_branchwater/src/fastmultigather_rocksdb.rs

Line 31 in e28c29a

let db = RevIndex::open(index, true, None)?;

sourmash_plugin_branchwater/src/manysearch_rocksdb.rs

Line 35 in e28c29a

let db = RevIndex::open(index, true, None)?;
