Closes #529

This adds a fast-rng feature that can be used to generate v4 UUIDs much faster than getrandom (which just falls back to OS APIs).

The quality of the random data is no less suitable with fast-rng than the fallback. It just requires more dependencies to build, and some users of uuid are very dependency-averse.
