Parallel iteration

EcsThreadHandler _handler;
public void Run(EcsPipeline pipeline)
{
    var group = _world.Where(out Aspect a);
    void Handler(ReadOnlySpan<int> entities)
    {
        foreach (var e in entities)
        {
            a.poses.Get(e).position += a.velocities.Read(e).value * _time.DeltaTime;
        }
    }
    group.IterateParallel(_handler ??= Handler, 1000);
}

NOTICE: The smaller the minimum size of the group part when dividing, the more threads can be utilized. In some situations, too many threads can negatively impact performance.

NOTICE: Inside the handler, creating/deleting entities, adding/removing components on entities is prohibited. Only modification of data within components is allowed.
