/**
 * 数组对象key值求和
 * @param target 目标对象
 * @param keys 需要求和的key数组
 * @return 求和后的对象
 * @category 对象Object
 * @example
 * ```ts
 * arrObjSum([{id: 1, age: 10, sx: 1}, {id: 2, age: 20, sx: 2}], ['id', 'age'])
 * // => {id: 3, age: 30}
 * ```
 * @example
 * 求和项不是数字时会以0处理
 * ```ts
 * arrObjSum([{id: 'a', age: 10, sx: 1}, {id: 2, age: 'b', sx: 2}], ['id', 'age'])
 * // => {id: 2, age: 10}
 * ```
