Added OnNpcTarget hook for new NPC types

If returning null, this hook is called very, very frequently. If returning anything other than null, it is called slightly less often than when returning null, but still more frequently than for the others NPCs.

I think this hook needs to be moved to another method because CanTarget is also called in other places.
For example, we can move it in the TickTargeting method, within the foreach loop, after CanTarget(item), or in the TrySetTarget method.

Rust.Ai.Gen2.SenseComponent.TickTargeting(float deltaTime)

Code before:

foreach (BaseEntity item in pooledList)
{
    if (CanTarget(item))
    {
        float num2 = base.baseEntity.SqrDistance(item);
        if (item.IsNpc)
        {
            num2 += 100f;
        }

        if (num2 < num)
        {
            num = num2;
            baseEntity = item;
        }
    }
}

if (baseEntity != null)
{
    TrySetTarget(baseEntity, bypassCooldown: false);
}

Code after:

foreach (BaseEntity item in pooledList)
{
    if (CanTarget(item))
    {
        ////////OR BEFORE CanTarget(item)
        object obj = Interface.CallHook("IOnNpcTarget", this, item);
        if (obj != null)
        {
            continue;
        }
        ////////

        float num2 = base.baseEntity.SqrDistance(item);
        if (item.IsNpc)
        {
            num2 += 100f;
        }

        if (num2 < num)
        {
            num = num2;
            baseEntity = item;
        }
    }
}

if (baseEntity != null)
{
    TrySetTarget(baseEntity, bypassCooldown: false);
}
