直接修改原先的 AddressParam 把里面的 is_seg_wit 字段改成 seg_wit 就可以了。 AddressParam 本来就是为了通用的 API 设计的，这样很多就是为了修改入参的代码也可以省了

这个方法和下面 sign_usdt_mixed_transaction 重叠代码非常多，看起来是可以合并到一起的

沿用了以前结构，如果合并就比较突兀，可以整体优化下

看到提出了一个 get_xpub_safe 方法，👍。不过这个函数还是超过 100 多行了，如果可以，将下面分成三部分似乎更好， 1. 判断 flag 和 path。2. 公私钥派生 3. 地址校验

130 这个魔法数字出现频率太高了，最好定义为一个常量。以免有些地方手误写错

这个函数快300行了，如果能分割成不同小函数读起来和后续代码重用应该都会方便很多。

native segwit 的path 应该是 m'/84'/1'/0'。不过这个关系不大

这个是之前native开发时，用错了path，涉及测试数据，在链上有对应，就不改了。 后来支持混合签名用的84
