Different versions of cavl2.h

Hello! Why OpenCyphal-Garage/cy/lib/cavl2.h not the same as OpenCyphal/libudpard/lib/cavl/cavl2.h but both version 2 w/o minor part? First file have function cavl2_root.

Thanks!

Cavl is a very simple library so a minor version number is unnecessary; for precise pinning use the git commit hash. Within the same major version the API is backward-compatible but new functions may be added.
