A thin rusty wrapper over the YuNet face detection network (aka libfacedetect).
Currently frozen to commit 40926655865c233b33d3de94302174efb6b5ac55.
At the moment, Rusty Yunet doesn't track the upstream YuNet repository, so any upstream patches must
be implemented manually. For the time being, these will be limited to significant bugfixes and security/safety
patches.
