Summary:
D24358369 (8a31e984b3) introduced a dependency outside the `sonar/` dir, which probably should not have happened. D27324576 finally broke this, by adding a dep to QPL core, which will never be installed in our CI.
This diff unbreaks that rewriting the require to a locally provided version of crc32, however this is a stop gap, and it would be great if someone would look into a sustainable solution :)
