ThreadUnsafeRandom is a random implementation that is identical to LegacyRandomSource behaviourally, but without the thread checks. SimpleThreadUnsafeRandom is ThreadUnsafeRandom except with its nextInt(int) function replaced with a faster but more biased implementation when bound is very large. Additionally, replace Level/Entity randoms with ThreadUnsafeRandom. This avoids the expensive CAS logic at the expense of losing the thread check.
