James Tucker	d0f3fa7d7e	util/fastuuid: add a more efficient uuid generator ... This still generates github.com/google/uuid UUID objects, but does so using a ChaCha8 CSPRNG from the stdlib rand/v2 package. The public API is backed by a sync.Pool to provide good performance in highly concurrent operation. Under high load the read API produces a lot of extra garbage and overhead by way of temporaries and syscalls. This implementation reduces both to minimal levels, and avoids any long held global lock by utilizing sync.Pool.
