EntityLookup sets

[metalgearsloth]

Most EntityLookupSystem methods take in sets now so rather than allocating a new set for every query (expensive), this means you can store a field on your system and just pass it in every time instead.
e.g.

private HashSet<Entity<IComponent>> _entitySet = new();

private void Method() {
  _entityList.Clear();
  _lookup.GetEntitiesInRange(Type, MapCoordinates, _entitySet);

  foreach (var ent in _entitySet)
  {
  }
}
