add owner for spore

[mingzhang96]

携带孢子球所属玩家信息 我们为每个孢子球赋予了他被哪个玩家吐出的信息。例如，某个孢子球被id为1的玩家吐出，那么这个孢子球会携带一个 owner 属性，并且值为1.

举个简单的例子，如果你在 obs_settings 中设置了 with_spore_owner=True，那么在你得到的孢子球信息中将会包含 owner 字段。如下所示：

[position.x, position.y, radius, owner]

当然，如果你同时设置了 with_speed=True，孢子球信息将会变成如下所示：

[position.x, position.y, radius, vel.x, vel.y, owner]
