 * @plugindesc 状态添加过程自定义插件
 * @author Salted Fish
 *
 * @help
 * ============================================================================
 * 介绍
 * ============================================================================
 * 该插件可以自定义状态添加过程，可以在状态添加前进行自定义的判断。
 * 添加前，提供一个回调函数，可以在添加前进行自定义操作。
 * this 指向 target Game_Battler
 *
 * ============================================================================
 * 使用
 * ============================================================================
 * 添加前的自定义操作，提供一个回调函数，可以在添加前进行自定义操作。
 * this 指向 target Game_Battler
 * <SF_StatesCustomAddtion_Before>
 * 代码
 * </SF_StatesCustomAddtion_Before>
 *
 * 提供参数：
 * - target：目标 Game_Battler
 * - stateId：即将添加的状态ID
 * 返回值：
 * {
 *    // 是否终止后续操作
 *    "result": true/false,
 *    // 需要添加的状态数组
 *    "statesAdd": [1, 2, 3],
 *    // 需要删除的状态数组
 *    "statesRemove": [1, 2, 3],
 *    // 需要刷新回合数的状态数组
 *    "statesRefresh": [1, 2, 3],
 * }
 * 后续操作：
 * - 如果 result 为 true，则终止后续操作
 * - 如果 result 为 false，则继续后续操作
 * - 如果 statesRemove 不为空，则删除 statesRemove 中的状态
 * - 如果 statesRefresh 不为空，则刷新 statesRefresh 中的状态回合数
 * - 如果 statesAdd 不为空，则添加 statesAdd 中的状态，
 *   这里不会再次触发添加前的自定义操作
 *
 * ============================================================================
 * 举例
 * ============================================================================
 * 1. 添加状态 125 前，
 *    如果目标已经拥有状态 124，则删除状态 124，添加状态 125
 *    否则，添加状态 125、
 * 
 * <SF_StatesCustomAddtion_Before>
 * var result = {
 *   "result": false,
 *   "statesAdd": [],
 *   "statesRemove": [],
 *   "statesRefresh": [],
 * };
 * if (this.isStateAffected(124)) {
 *   result.statesRemove.push(124);
 *   result.statesAdd.push(125);
 * }
 * else {
 *   result.statesAdd.push(125);
 * }
 * return result;
 * </SF_StatesCustomAddtion_Before>
 *
 *============================================================================
 * 举例2
 *============================================================================
 * 2. 添加状态60前，
 * 生成整随机数1~10，如果随机数小于等于5，则添加状态148
 * （随机数结果不影响状态60）的添加
 * 
 * <SF_StatesCustomAddtion_Before>
 * var result = {
 *   "result": false,
 *   "statesAdd": [],
 *   "statesRemove": [],
 *   "statesRefresh": [],
 * };
 * result.statesAdd.push(60);
 * var random = Math.floor(Math.random() * 10 + 1);
 * if (random <= 5) {
 * result.statesAdd.push(148);
 * }
 * return result;
 * </SF_StatesCustomAddtion_Before>
 *
 * 
 * ============================================================================
 * 已知问题
 * ============================================================================
 * - 与状态叠加插件和状态覆盖插件不兼容。
