This commit updates the index allocation performed in the pooling allocator with a few refactorings: * With `cfg(fuzzing)` a deterministic rng is now used to improve reproducibility of fuzz test cases. * The `Mutex` was pushed inside of `IndexAllocator`, renamed from `PoolingAllocationState`. * Randomness is now always done through a `SmallRng` stored in the `IndexAllocator` instead of using `thread_rng`. * The `is_empty` method has been removed in favor of an `Option`-based return on `alloc`. This refactoring is additionally intended to encapsulate more implementation details of `IndexAllocator` to more easily allow for alternate implementations in the future such as lock-free approaches (possibly).
