<!-- Please describe your changes on the following line: -->
This PR implements an in-memory random number generator that only uses an OS RNG for (re)seeding. The OS RNG is shared, so there's only one file descriptor for `/dev/urandom` being used.
The PR also implements a tidy check that we don't accidentally introduce an RNG. Rather annoyingly, there are a lot of transitive dependencies on `rand`, notably hash maps in `std`.
This PR makes it possible to use uuids for identifiers such as pipeline and frame ids.
