based on twox-hash upstream's changelog, 2.x is a complete rewrite with a
lot of interface changes, so it likely is best to ask sourmash's upstream
whether they are planning on migrating any time soon. if not, somebody
needs to either do this migration in Debian and try to upstream it, or
we'd need to re-introduce twox-hash 1.x as a separate source package..
