this seems to be the exception of the usual "C-lib bundled with Rust crate",
the C sources are actually part of the same upstream, developed and released
together and hopefully intentionally published on crates.io

if that last part is confirmed with upstream, I see no reason not to build
a proper C shared library as part of the package build. it might make sense
to package it in a more custom fashion from upstream git then (as most of
the debcargo generated packaging files will need to be overridden), and
combine it with (rust-)b3sum as well.
