[Enhancement] RequireComponent Attribute

[inmny]

It is common to assign RequireComponent for a self-defined component in Unity for easier initialization.

Like this:

class SubComponent : MonoBehaviour {}

[RequireComponent(typeof(SubComponent), typeof(SpriteRenderer))]
class CustomComponent : MonoBehaviour {}

var obj = new GameObject("Test", typeof(CustomComponent));

// Then obj has CustomComponent, SubComponent, SpriteRenderer together.

Is it possible to implement it in Friflo? like this:

[RequireComponent(typeof(Position))] 
struct AnimData : IComponent 
{
    public int frame_idx;
    public Sprite[] ref_frames;
}

var e = store.CreateEntity(new AnimData());
// Then e has both AnimData and Position components.

To my knowledge, it is possible to expand Generic<AnimData>.ComponentTypes through the attribute,

Thought about this.
It is possible but doing this has a performance impact on all AddComponent<> and CreatEntity() operations. Whether with or without this attribute.

Additionally understanding of code is more complicated because components may be added implicit.
You now have to check component type attributes when adding them.
Otherwise you will wonder why a component was added without doing this explicit.
